Tools for ozone monitor calibration and bump-testing

Ozone monitors and sensors should be calibrated every 6-months to 1-year. This calibration can be done by our technicians to a NIST traceable standard. However, if this is something you prefer to perform on-site we have a few tools you can use to perform calibrations on-site, or bump-test your ozone monitor between calibration intervals.

Model 306 Calibration Source

The Model 306 Calibration Source is a UV based ozone source that is portable and easy to use.  This device will provide a known quantity of ozone gas in a sample stream of 3 LPM.  Three usable settable ozone ranges are available to choose from for calibration.  This will allow the calibration of most ozone sensors that have a calibration adapter or a flow-cell where gas can flow to or through the sensor for calibration. This device requires no zero air cylinder and can use ambient air for ozone sensor calibrations.  The accuracy of this device is 2% which is superior to any other portable calibrator available on the market.

A23-14 Ozone Calibrator

The A23-14 Ozone calibrator is used to calibrate your ozone sensors. This device creates a known level of ozone with the factory calibrated ozone generator. Easy to use, and portable this unit can be carried to your ozone sensor.  Accurate to within 5-10% depending upon the application.

Ozone Puffer

The ozone puffer is a simple to use tool to bump-test ozone sensors. Portable and battery powered, this is the easiest method to quickly bump-test your sensor between calibration intervals.  Battery powered unit requires no power cord and is completely portable.

Bump testing is a great method to ensure your sensor is responding to ozone when necessary. Bump testing is not a replacement for calibration. However, bump testing can be done between calibrations to ensure proper response of your ozone sensor, and ensure that a sensor failure has not occured. We suggest bump testing your ozone monitor as often as daily in extremely critical applications. Weekly or montly internvals are common for bump testing your sensor between annual calibration periods.

OG-3 Checker

The OG-3 Calibration Checker is primarily used for Eco-Sensors devices. This will create a known ozone level for bump testing or checking calibration of your sensor between calibration intervals.

Ozone Chambers

We can also provide complete ozone chambers to be used for calibration purposes.  We build standard and custom ozone chambers for ozone exposure testing.  These chambers can also be used for calibrating one, or multiple ozone sensors at one time.  Using a calibration chamber any level of ozone desired can be chosen and entered into the control system, the chamber will maintain that ozone level, by placing your ozone sensors inside the chamber you can validate the readings of your ozone sensors and adjust accordingly.

Updated Calibration Chamber

Recently Oxidation Tech updated our calibration chamber and process.  We have been using a smaller chamber or individual processes to calibrate each sensor we receive one by one.  With our new calibration chamber, we can calibrate as many as 10-15 ozone monitors at one time.

This calibration chamber still uses our Thermo Fischer Transfer Standard Ozone Analyzer to measure and control ozone levels inside the chamber.  However, with the use of an external ozone generator and automated control system a precise ozone level can be maintained inside the chamber at all times.  This saves time and potentially provides a higher quality, more accurate calibration for your device.

Our ozone calibration chamber can also be used to high range calibrations up to 1,000 ppm, or can be used for ozone exposure testing.  As this sealed chamber has great capacity and automation any device a customer may need to be exposed to ozone can be placed in the chamber to be exposed to known and tightly controlled ozone levels.

We also offer ozone exposure testing for higher range ozone levels, and lower range ozone levels in a smaller chamber.  Ozone exposure chambers are also a part of our standard product line as these are a popular requirement for many material testing facilities.
