Sensor Calibration
Why must you calibrate gas sensors? Calibration is recommended to ensure maximum accuracy and safety. It verifies the sensor is accurate and providing correct measurement of the gas you are detecting.
How often should I calibrate my sensor? Factory calibration should be done annually. But we also recommend field check or bump test every 6 months. Different gasses and sensor manufacturers have different requirements. You can view their specific requirements using the links below:

Factory Calibration
Your sensor can be sent back to us for calibration. We will evaluate, calibrate, and return it with a Calibration Certificate providing performance during calibration, date it was calibrated, and date that calibration should be done next.
How do I return my sensor to be calibrated?
Your sensor can be sent back to us at:
Gas-Sensing
Attn: Calibration
1322 1st Street
Hull, IA 51239
We require that an RMA form be filled out and sent back with your sensor. Contact us to receive this form.
Calibration Gasses
Another option is to get gas cylinders of known quantities of gas. This can be mixed with air to provide span calibration. This needs to be done according the manufacturers specifications to perform a span gas calibration. NOTE: This is not an option for all gases as some have a short half-life and cannot be bottled.
Some gases can be calibrated on site using a calibration kit. For example: the A23-14 provides a consistent flow of calibrated ozone gas for calibration purpose, in a handy portable carry case.
Gas Calibration Kits can be found on our website.
Field Calibration
Field calibration can be performed on-site and is convenient when sending your sensor in to be calibrated is challenging. In order to perform field calibration you must have calibration gasses or a unit designed to produce a consistent amount of gas, that way you can ensure the sensor is reacting properly.
Gas Sensing is will to come to your facility and perform Field Calibration.
Bump Testing
Bump testing allow you to check and make sure that your sensor is responding to the gas that you are trying to detect. It is not a precise measurement, but rather, just a check to ensure your monitor is reacting and will respond when gas levels reach a dangerous level. This is not a replacement for calibration.
