In-House Repair– Industrial Ozone Generator

Oxidation Tech can repair nearly all Industrial Ozone Generators back to original specifications. Many Ozone Generators have been built/integrated by ozone companies that either no longer exist, or offer no repair services. In these cases, we are able to help. We will repair many obsolete Ozone Generators from manufacturers that do and do not exist today. Of course, we would also be glad to repair any current models of Ozone Generator. Our experience and knowledge allow us to repair your Ozone Generator in a timely manner at a very competitive cost.

Many Ozone Generators today use the same internal components provided by only a handful of manufacturers. There are relatively few Ozone Generators that are manufactured from completely exclusive components. Therefore, repairs of many brands of Ozone Generators use the same internal components. Also, there are now aftermarket parts available to replace the commonly used components in many Ozone Generators. So, before you give up on that older Ozone Generator, or are told your Ozone Generator is obsolete, give us a call!

Our on-site repair labor rates for Industrial Ozone Generators = $75/hour.

We do not charge a fee for diagnostics of your Ozone Generator. We will diagnose the repair and quote a repair price for your Ozone Generator at no cost. If you decide not to repair the Ozone Generator we will only charge for return shipping of your equipment.

 

 

In-House Repair– Commercial (air blower style) Ozone Generator

Ozone is very commonly used for air treatment in many applications. Many manufacturers, large and small, have produced Ozone Generators for air treatment that blow ambient air over a UV lamp, or corona discharge element to produce ozone from the ambient air in a room. We refer to these type of units as commercial, or air blower style Ozone Generators.

We stock many aftermarket and original OEM repair parts for these Commercial Ozone Generators. The components used are frequently interchangeable between units; therefore repair costs are frequently low.

If you have a Commercial Ozone Generator in need of repair, give us a call. We would be glad to diagnose and quote a repair cost of your Ozone Generator.

Our in-house repair labor rates for Commercial Ozone Generators = $65/hour.

We do not charge a fee for diagnostics of your Ozone Generator. We will diagnose the repair and quote a repair price of your Ozone Generator at no cost. If you decide not to repair the Ozone Generator we will only charge for return shipping.

ECOSENSORS CALIBRATION INFORMATION

EcoSensors devices have a variety of different sensors and calibration options and prodedures.  These will vary by product and sensor used in that product.  See the list below for your specific sensor and relevant calibration information.  First, follow our short list of FAQ’s to familirize yourself with general calibration inforamtion.

ECOSENSORS FAQ AND GENERAL INFORMATION

WILL I GET A CALIBRATION CERTIFICATE?

Yes, all EcoSensors products are shipped with a recent calibration certificate showing NIST traceability

HOW OFTEN SHOULD MY SENSOR BE CALIBRATED?

Factory calibration should be performmed annually on all EcoSensors products to ensure maximum accuracy and safety.

CAN I BUMP-TEST MY ECOSENSORS PRODUCT?

Yes, most EcoSensors products measure ozone.  A small ambient air ozone generator can be used to bump test the sensor.  These are low cost and readily available.

The C-21, and C-12 are VOC sensors.  A simple Sharpie marker near the sensor will be a great bump test.  Sufficient VOC gasses are emiited from an uncapped marker to bump-test these sensors.

EcoSensors Product line
 

ECOSENSORS PRODUCTS

A-22, OS-6, OS-4, SM-X, SM-4, SM-6 AND SM-7

These sensors all use the SM-X ozone sensor chip. 

SM-X Replacement Ozone Sensor

The SM-X is a mass proeduced, yet accurate ozone sensor that is considered disposable.  There is no calibration option for this esnsor.  The expectation is that this $150 sensor chip is replaced annually with a new sensor chip.  The SM-X is only available in one range, 0-20 ppm, each device may use that data and display differently, however we keep it simple and can use the same sensor for each device listed above.

The SM-X carries all calibration data, along with a humidity sensor for humidity compensation that is calibrated to work with the sensor.  No calibration alterations are necessary or possible with the SM-X sensor chip.

Each of these sensors calibration can be checked throughout the year, using the OG-3 Calibration Checker.  The OG3 will easily and quickly verify that the SM-X incorporated on your device is still accurate and reading ozone correctly.

 

OEM-1, OEM-2, AND OS-3

Note: the OS-3 Ozone Sensors are not currently in production, however we can service these devices as long as they continue to function in your application.

These devices all use the SM Replacement Ozone Sensors.

SEN-1 Replacement zone Sensor

These sensors are not designed to be calibrated or serviced after getting put in use.  Therefore the sensor is simply replaced with new, and the old sensor is disposed of.  No return policy is required for the old sensor.  The cost of the replacement sensor is only $99.  This low cost is lower than any factory calibration offered by any vendor we are aware of!

The spare sensor module is availabe in 3 ranges, 0.1, 1.0, and 10.0 ppm (part numbers, SM-0.1, SM-1.0, and SM-10) The OEM-1 can be used interchangeably with any of these three sensor ranges.  However, the OEM-2 and OS-3 are built and calibrated for one sensor range, ensure you purchage the right sensor range for your device.

Purchase Spare sensor Modules HERE

Each of these sensors calibration can be checked throughout the year, using the OG-3 Calibration Checker.  The OG3 will easily and quickly verify that the SEN-1 incorporated on your device is still accurate and reading ozone correctly.  While the OEM-1 and OEM-2 do not have displays, there is a method to verify calibration.  The OEM-1 offers a 0-1 VDC ouput that is linear with the range of your sensor.  The OEM-2 provides a 4-20mA output that is linear with the rage of your sensor.  Using a multimeter, or volt meter you are able to verify sensor readings without a display.

EX-1X, A-21ZX, C-30ZX, AND OS-1X

Note: the OS-1X Ozone Sensors are not currently in production, however we can service these devices as long as they continue to function in your application.

These devices all use an integrated sensor.  The best option for calibration is to ship the sensor back to Gas Sensing, or EcoSensors to have a factory calibration performed.  Most often, after 1-year of use the sensor needs to be replaced.  The sensor in these deivces is soldered onto the board and not replaced without some labor.  Follow this link, for detailed instructions on sensor replacement.

If you do choose to purcahse and install your own replacement sensor, they are available for a price of $75 each.  It is the same sensor for each device listed here.

Contact us for information in shipping your sensor to us for factory calibration.  Calibration cost is $225.  This includes the price for a replacement sensor.

Each of these sensors calibration can be checked throughout the year, using the OG-3 Calibration Checker.  The OG3 will easily and quickly verify that the sensor incorporated on your device is still accurate and reading ozone correctly.

 

C-21 VOC SENSOR

The C-21 is a great VOC sensor that can be calibrated and adjusted to respond to many VOC gasses quite accurately.  Eco-Sensors calibrates each C-21 to generic VOC gasses from the factory.

Bump testing of your VOC sensor can also be performed.  We suggestion using something simliar to a common Sharpie marker.  These are common, and off-gas a great deal of VOC gasses.  Placing this near your C-21 will ensure the sensor is still responsive to some VOC gasses.

Testing the VOC sensor with a Sharpie

The C-21 VOC Sensor can be calibrated to your specifications using detailed instructions provided at the link below:

C-21 VOC Sensor Calibration Instructions

Replacement sensors for the C-21 are available from Gas Sensing for $50.  Please contact us for ordering information.

Contact us for information in shipping your sensor to us for factory calibration.  Calibration cost is $125.  This includes the price for a replacement sensor.

UV-100 OZONE ANALYZER

The UV-100 Ozone Analyzer is a UV based instrucment that is extremely accurate, and extremely sensitive.  Great care should be taken with any calibration or lamp replacment.

Calibration of the UV-100 can be peformed by obtaining an ozone reference standard and entering the admin menu of the UV-100.  The Zero, and Span settings of the UV-100 can be altered in that menu.

The UV-100 UV bulb can be field replaced using the following instructions:

UV-100 lamp replacement Instructions

After the UV lamp has been replaced calibration is required.  This can be performed by using a reference standard to perform calibration.

Replacement UV-Lamp = $200

Factory Calibration of the UV-100 = $325

Contact us for information in shipping your device to us for factory calibration.

OG-3 CALIBRATION

The OG-3 is a calibration checker designed and built by EcoSensors specifically for EcoSensors products.  The OG-3 is a great low cost reference standard for EcoSensors products.  A UV-lamp is used to produce a known amount of ozone from the OG-3.  It is usually calibrated to 0.1, 1.0 or 10.0 ppm.

The OG-3 ozone output should be checked and adjusted periodically (depending upon use) to kep it accurate.  We provide calibration service and repair for the OG-3.

OG-3 Calibration = $150

OG-3 lamp replacement (includes calibration) = $325

Replacement OG-3 Lamp = $175

Contact us for information in shipping your sensor to us for factory calibration.

Using the UV-100 Ozone Analyzer the OG-3 ozone output can be verified and adjusted as needed.  See details on this process at the link below:

OG-3 Calibration Instructions using the UV-100 Ozone Analzyer

The UV lamp used inside the OG-3 will get weak and require replaceemnt after some time.  If you find your OG-3 lamp is in need of replacement we can provide service to replace this lamp, or you can purchase a lamp from us, install, and calibrate your OG-3 with a UV-100 Ozone Analzyer.

ATI SENSOR CALIBRATION

ANALYTICAL TECHNOLOGIES INCORPORATED (ATI)

This information applies to the sensor module used in the C16, F12, and D12 Monitors.

ATI Smart Sensors come pre-calibrated and have all calibration information loaded on the sensor.  The sensor can be swapped between monitors without any special requirements for proper calibration.

Sensors are fairly low cost and are replaced annually to remain in calibration.  Periodic bump tests can be performed to ensure the sensor is still operating, but no calibration is typically necessary.

ATI Product List

 Calibration Frequency

While the transmitter itself requires no periodic calibration, H10 sensors should be “zero” and “span” calibrated every 3-6 months, based upon environmental factors. Sensors frequently exposed to dirt, oil mist, vapors, or very dry air, may require more frequent calibration.

Zero Calibration

As the name implies, zero calibration corrects the transmitter reading to zero in the absence of any reactive gas. During zero calibration, the transmitter offset error is stored, and subsequently subtracted from future readings. ATI recommends bottled zero gas as a source, which should be selected based on the type of sensor. For example, bottled “Zero” Air may be used to zero Chlorine sensors, but Oxygen sensors require bottled Nitrogen gas.

Span Calibration

The role of span calibration is to correct the transmitter reading to a known concentration of target gas (the gas for which the sensor was designed to monitor). During span calibration, the transmitter effectively stores the slope of the error, and divides it out of subsequent readings. Sensors for most gases, such as Ammonia, require a bottled “span gas” source. This applies even to Oxygen sensors, where the span gas source is bottled zero air.

Calibration Terminology

The zero calibration is referred to as, “zero”, “zeroing”, and “zeroed”. Likewise for the span calibration, which appears as, “span”, “spanning”, and “spanned”. As with most instruments, zero calibration should be performed before span.

Calibration Kits

Calibration kits, containing zero and span bottle gas sources, are available from ATI for many toxic gases. Contact Gas Sensing, if you have questions about calibration gas kits or gas sources.

ATI does provide a special kit for ozone gas calibration as ozone cannot be supplied in a calibration gas cylinder.  The A23-14 can be used for all ATI ozone products along with other ozone sensors. Contact gas sensing for details.

A23-14 Ozone Calibration Kit

Indications During Sensor Calibration

The “un-blanked” gas concentration value is displayed during zero and span calibration, primarily to observe any slight amount of positive or negative drift. In addition, alarms are cleared and inhibited, and the 4-20mA output of the F12 transmitter is locked at 4.0mA (transmitters equipped with Oxygen sensors are locked at 17.4mA, representing normal, 20.9% atmospheric Oxygen). The 4-20mA output will not change when gas is applied and removed, and for 15 minutes thereafter (the default value). While viewing the calibration pages, the LCD display will indicate the changing gas concentration.

Calibration Exceptions

Zero and span calibration are not allowed during the following conditions: v Sensor removed, or in 5-minute8 warm-up period v Transmitter fault is active v Auto-test is active (“A” status indicator appears on Main Display page) To help prevent errors, zero and span are not allowed if the sensor output, or span value entered, is too high or too low. Memory errors are reported if detected while updating the sensor or transmitter memory.

Zero Calibration Procedure

Performing a zero calibration requires bottled “Zero-gas” with a 500 cc/min regulator, calibration adapter, and a convenient length of ¼” tubing. The gas used depends on the type of sensor installed. For example, an H2S sensor may be zeroed with Zero-air, while Oxygen sensors must be zeroed with Nitrogen. In some cases, a sensor may be zeroed directly to the atmosphere, but only when it is known to be free of reactive gasses. Check with the factory if you are uncertain about which gas to use.

ATI zero gas calibration diagram

Span Calibration Procedure

Span calibration* requires bottled “span-gas” with a 500 cc/min regulator, calibration adapter, and a convenient length of ¼” tubing. The gas type and concentration used depends on the type of sensor installed. Check with the factory if you are uncertain about which gas to use.

 Sensor Calibration Records

A calibration record is written into the sensor memory each time a zero or span calibration is performed, and when a calibration Undo is performed. Enough memory is reserved for 63 zero calibrations and 63 span calibrations. Zero and span calibration records are accessed on the Cal_History page.

Auto-test

The Auto-test option verifies the serviceability of the transmitter on a prescribed schedule by exposing the sensor to a small amount of gas, and verifying a minimum response. Three attempts per test are made, and if the sensor does not respond on the third attempt, a fault alarm is triggered (may be optionally disabled). A summary of pass, fail, and retry counts are maintained in the sensor memory, and may be viewed on the Auto-test History page.

ATI auto test generator

F12 with auto-test generator option

 

 

The auto-test generator plugs into the bottom of the sensor holder and is connected to the monirot base.  On a timed sequence the Auto-Test generator will test the sensor response to verify that the sensor will still respond to the necessary gas properly.

Ozone Sensor Calibration Information

CALIBRATION INFORMATION

Ozone Sensor Calibration Information

All Ozone Sensors will require periodic calibration to ensure your gas measurements are accurate and correct.  Different gasses, and sensor manufacturers will have differing requirements and methods for calibration.  This page will serve to provide general calibration information and links to specific calibration procedures from the sensor manufacturers we represent.

Should you have any questions about sensor calibration, or would like us to help you with your calibrations please contact us.

CALIBRATION FREQUENCY

Most sensor manufacturers will recommend calibration annually.  This would be the longest interval Ozone Services would recommend for ozone sensor calibration.

The frequency of calibration will be depending upon the gasses measured, sensor type, and purpose of the ozone sensor.

Our general recommendation would be to perform a bump-test of the sensor at least monthly.  Perform a field or factory calibration or sensor check every 6-months, and a factory calibration or sensor replacement every 12-months.

 

NIST (NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY)

Have you ever wondered who ensured 1 pound is exactly 1 pound?  and 1 meter is precisely 1 meter? The NIST is the answer.  this is the governing board that will hold the standard of measurement.

Every gas measurement calibration standard must be directly traceable to the NIST to ensure your sensors calibration is accurate.  When you are reviewing your calibration certificate it must be clearly stated that the calibration standard used to calibrate your sensor is NIST traceable.  If necessary, you can, and should request the proper documentation to validate that traceability.

Calibration gasses can also be NIST traceable The NIST has set-up specific protocols for manufacturers of calibration gasses to follow to ensure your cal gas can be provided with NIST traceability.

 

CALIBRATION GASSES

Calibration gasses are used to calibrate many gas sensors.  Known quantities of gas can be mixed with air to provide a span calibration gas to be used for calibration.  For example. if you are calibrating a chlorine sensor and would like to perform a span gas calibration at 5 ppm, you would purchase a cylinder of air mixed with exactly 5 ppm of chlorine.  This gas can be used according to the manufacturers specifications to perform a span gas calibration.

Ozone is a gas that must be produced on site in known quantities to perform calibration.  The only option for precise ozone gas sensor calibration is sending your sensor to a facility that has a specially build calibration chamber.

FIELD CALIBRATION

Field calibration is just what it indicates.  Any calibration of a sensor performed in the field, or where the sensor is currently installed.  This can be performed with calibration gasses, or with devices designed to produce gasses that will react properly to ensure calibration is accurate on your sensor.

Field calibration is convenient for applications where many sensors are installed and would be challenging or inconvenient to send away for calibration.  Field calibration of your sensors can be performed by Gas Sensing, and many other service companies that will calibrate, and repair your sensors.

 

WHAT IS BUMP TESTING?

When you want to know if your sensor is responding a bump test is a great option.  This is simply a test that exposes the sensor to the specific gas it is intended to measure and ensure that the sensor does indeed respond.  While not a precise process, this does ensure that the sensor is indeed responding and can respond in a critical situation where human safety is critical.

ATI offers an Auto-Test generator for many of the sensors used on the D12 and F12 monitors.  This auto-test generator will produce a gas that causes the proper sensor to react.  A test is run on a pre-set schedule if the gas sensor does not respond as expected an alarm will come on indicating the sensor has failed.  This is a great option for gas sensing is critical applications.

Note: A bump-test is not an acceptable replacement for sensor calibration

 

BUMP TESTING VS CALIBRATION

Bump testing is a great method to ensure your sensor is responding to the gas it is intended to measure.  Bump testing is not a replacement for calibration.

Calibration verifies that the sensor is accurate and providing correct measurements.

 

ZERO CALIBRATION

Zero calibration ensured the sensor is reading an accurate 0, or pure air situation.  Most sensors have an easy way to reset the zero in the event that it drifts over time.

 

SPAN CALIBRATION

Span calibration is ensuring the actual measurement of gas is accurate.  The span should be done at a level of gas that would normally be measured.  Create a known amount of gas at a specific level and verify the sensor displays the same level of gas.

 

CALIBRATION CERTIFICATE

A calibration certificate is provided by the manufacturer when you purchase a sensor.  The calibration certificate provides you with the necessary information to prove that the sensor was calibrated to an NIST standard.  The Calibration Certificate will provide the date the sensor was calibrated, and the date calibration should be done again.
