Quick Overview

     Calibration Period? 


    We typically suggest 6 to 12 months. This time period is typical for gas detectors employing electrochemical or catalytic bead sensor elements. Be attentive and calibrate much more regularly if:

    • The user is employing the device as an analytical tool where accuracy is paramount.
    • The user is using the device in an extreme environment (temp and humidity).
    • The user is undertaking a imminently dangerous or extreme application. Calibration and bump testing is mandatory since imminent injury or death will occur if the device fails.
    • Follow good practice and bump test to ensure operation.

     Who Calibrates?   

    There are 2 options:

      • Some customers calibrate the device themselves. See below for instructions and videos.
      • We can calibrate your device. The calibration services we offer includes:
    ** Note: Ozone (O3) is a unique gas and cannot be calibrated with a calibration bottle setup. Ozone must be generate and the source calibrated to ensure accurate detector calibration. 



       To calibrate a detector yourself, ensure you have the following:

      • Calibration Cap: Where required, calibration caps are included with the purchase of a detector.
      • Gas Bottle: Recommended calibration gas bottles: Click Here
      • Regulator: Recommended gas bottle regulator 0.5-1.0 LPM: Click Here
      • Tubing: Recommend 1/8" ID silicone tubing. Click Here

       Calibration & Bump Test Steps?

      • Calibration procedures are highlighted in each respective product user manual.
