Ozone Sensor Calibration Information<\/a><\/h2>\n

All Ozone Sensors will require periodic calibration to ensure your gas measurements are accurate and correct.\u00a0 Different gasses, and sensor manufacturers will have differing requirements and methods for calibration.\u00a0 This page will serve to provide general calibration information and links to specific calibration procedures from the sensor manufacturers we represent.<\/p>\n

Should you have any questions about sensor calibration, or would like us to help you with your calibrations\u00a0<\/span>please contact us.<\/a><\/p>\n

<\/h3>\n

CALIBRATION FREQUENCY<\/strong><\/h3>\n

Most sensor manufacturers will recommend calibration annually.\u00a0 This would be the longest interval Ozone Services would recommend for ozone sensor calibration.<\/p>\n

The frequency of calibration will be depending upon the gasses measured, sensor type, and purpose of the ozone sensor.<\/p>\n

Our general recommendation would be to perform a bump-test of the sensor at least monthly.\u00a0 Perform a field or factory calibration or sensor check every 6-months, and a factory calibration or sensor replacement every 12-months.<\/p>\n

 <\/p>\n

NIST (NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY)<\/strong><\/h3>\n

Have you ever wondered who ensured 1 pound is exactly 1 pound?\u00a0 and 1 meter is precisely 1 meter?\u00a0The NIST is the answer<\/a>.\u00a0 this is the governing board that will hold the standard of measurement.<\/p>\n

Every gas measurement calibration standard must be directly traceable to the NIST to ensure your sensors calibration is accurate.\u00a0 When you are reviewing your calibration certificate it must be clearly stated that the calibration standard used to calibrate your sensor is NIST traceable.\u00a0 If necessary, you can, and should request the proper documentation to validate that traceability.<\/p>\n

Calibration gasses can also be NIST traceable<\/a>.\u00a0\u00a0<\/span>The NIST has set-up specific protocols<\/a>\u00a0<\/span>for manufacturers of calibration gasses to follow to ensure your cal gas can be provided with NIST traceability.<\/p>\n

 <\/p>\n

<\/h3>\n

CALIBRATION GASSES<\/strong><\/h3>\n

Calibration gasses are used to calibrate many gas sensors.\u00a0 Known quantities of gas can be mixed with air to provide a span calibration gas to be used for calibration.\u00a0 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.\u00a0 This gas can be used according to the manufacturers specifications to perform a span gas calibration.<\/p>\n

Ozone is a gas that must be produced on site in known quantities to perform calibration.\u00a0 The only option for precise ozone gas sensor calibration is sending your sensor to a facility that has a specially build calibration chamber.<\/p>\n

<\/h3>\n

FIELD CALIBRATION<\/strong><\/h3>\n

Field calibration is just what it indicates.\u00a0 Any calibration of a sensor performed in the field, or where the sensor is currently installed.\u00a0 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.<\/p>\n

Field calibration is convenient for applications where many sensors are installed and would be challenging or inconvenient to send away for calibration.\u00a0 Field calibration of your sensors can be performed by Gas Sensing, and many other service companies that will calibrate, and repair your sensors.<\/p>\n

 <\/p>\n

WHAT IS BUMP TESTING?<\/strong><\/h3>\n

When you want to know if your sensor is responding a bump test is a great option.\u00a0 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.\u00a0 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.<\/p>\n

ATI offers an Auto-Test generator for many of the sensors used on the D12 and F12 monitors.\u00a0 This auto-test generator will produce a gas that causes the proper sensor to react.\u00a0 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.\u00a0 This is a great option for gas sensing is critical applications.<\/p>\n

Note: A bump-test is not an acceptable replacement for sensor calibration<\/em><\/p>\n

 <\/p>\n

BUMP TESTING VS CALIBRATION<\/strong><\/h3>\n

Bump testing is a great method to ensure your sensor is responding to the gas it is intended to measure.\u00a0 Bump testing is not a replacement for calibration.<\/p>\n

Calibration verifies that the sensor is accurate and providing correct measurements.<\/p>\n

 <\/p>\n

ZERO CALIBRATION
\n<\/strong><\/h3>\n

Zero calibration ensured the sensor is reading an accurate 0, or pure air situation.\u00a0 Most sensors have an easy way to reset the zero in the event that it drifts over time.<\/p>\n

 <\/p>\n

SPAN CALIBRATION
\n<\/strong><\/h3>\n

Span calibration is ensuring the actual measurement of gas is accurate.\u00a0 The span should be done at a level of gas that would normally be measured.\u00a0 Create a known amount of gas at a specific level and verify the sensor displays the same level of gas.<\/p>\n

 <\/p>\n

CALIBRATION CERTIFICATE<\/strong><\/h3>\n

A calibration certificate is provided by the manufacturer when you purchase a sensor.\u00a0 The calibration certificate provides you with the necessary information to prove that the sensor was calibrated to an NIST standard.\u00a0 The Calibration Certificate will provide the date the sensor was calibrated, and the date calibration should be done again.<\/p>\n
