Gas Detector Calibration

If you're tired of paying companies $85-$120 for gas detector calibration, why not calibrate your own? High prices for gas detector calibrations unfortunately lead some companies to unsafe practices (like not bump testing daily or only calibrating every few months) and we'd much rather teach you to calibrate your own monitors more regularly on your own. That's why we're currently in production of videos on how to calibrate every gas detector out there, starting with portable units and eventually moving to fixed gas detection calibration. Don't see a gas detector on our page that you need to know how to calibrate? Contact Us and we'll put it to the top of the list or walk you through over the phone.  To view our gas detector calibration videos, head over to our Gas Detector Information page.

To read an article written on how to set up a clean gas detector calibration program, as well as avoid some of the more prevalent myths and legends out there, click here to see our article published in Occupational Health and Safety Magazine.

Already know how to calibrate your gas detector but can't remember what calibration gas to use or what flow rate regulator is necessary?  Check out our Calibration Gas Guidelines below for the manufacturer recommendation.  You can purchase any of these blends from our friends over at Ideal Gases, who manufacture the gas just south of Detroit, MI.  If you don't see your gas monitor on there, hit the Contact Us page and we'll help you out.

Read all of this and still want us to calibrate your gas monitor for you?  We would be glad to!  Head over to the Contact Us page and send us a message.  We'll tell you how long the current time is for a gas monitor calibration and how much you can expect the bill to be.  For normal calibration gas blends, we charge $51 for a calibration.  If you've changed the monitor and need something special or different, it's $85 for a calibration.

 

Gas Detector Calibration Videos

The videos below will show you how to calibrate a number of the different gas detectors out there.  We hope they help you to calibrate your own monitors.  If you have a problem during the calibration, head on over to the Contact Us page and let us know what's happening, we'll try and walk you through the process. Feel free to let us know if you have a gas monitor not listed here that you need help with as well.

 

Gas Detector Calibration Gas Defaults

Please DO NOT take the values below as gospel.  ALWAYS check your gas detector to be certain you are using the correct calibration gas for the monitor.  Calibration gas values can be edited by the user in most detectors, so make sure your monitor is reading the same values on your bottle of calibration gas.  We make no guarantees that these numbers are correct, and manufacturers may change their values over time without notifying us.  

If you need calibration gas and don't know where to purchase it, you can buy it from our friends at Ideal Gases, Inc. Or you can head over to our Gas Monitor Information page, find your gas monitor, and click on the button that says "Buy Calibration Gas."
