Calibration & Bump Testing a Gas Detector

A gas detector is a life saving device and as such it is important to ensure that the gas monitor is fit for purpose and in accurate working order. Ways to check a gas detectors accuracy is by bump/challenge testing and or calibration using the right gases for the sensors installed.

The Gas Detector Shop offers a range of portable gas detector calibration services within Brisbane and Australia wide. Our qualified and factory trained technicians can calibrate and service most portable gas detectors. 

How often do you need to calibrate a gas detector?

Australian Standards and each Manufacturers Specifications will list the recommended frequency for the calibration of portable gas detectors. Other environmental factors that will need to be taken into consideration for determining if a portable gas detector requires calibration are:

• the sensor’s operating time
• conditions of use
• user experience
• contamination and exposure to hazardous materials

Most manufacturers recommend re-calibration at least every six months or 180 days and or earlier if the sensors drift.

What does bump test mean?

A bump test (also known as challenge test) when the operator exposes the monitor to known gas concentrations for a set time range to test the units response to the gases. This test also confirms that the detector's audio and visual alarms are in working order meaning that out in the field you will be able to hear/feel/see when your detector goes into alarm if/when exposed to gas.

It is recommended that Portable Gas Detectors be bump testing daily or Prior to each Use, and if the detector fails the bump test, requires re-calibration.

Can I calibrate my gas detector myself?

Yes with the right equipment you can manually calibrate your gas detector or automatically using a compatible Calibration Docking System or through manual calibration using the right gases, regulator and calibration cap & hose (normally supplied on purchase of your gas monitor)
