Don’t risk gas detection failure



Crowcon recently learnt that less than one third of managers are ‘very confident’ that the gas detectors in their workplaces actually work. Research also shows that, despite ranking the frequency of testing as most important, two in five managers believe their systems are not tested regularly.

And when asked about the procedure should all the gas detectors in a plant have failed, alarmingly almost a 25% of managers would carry on as normal.

These findings come from industry-wide research into fixed gas detection systems in the workplace, commissioned by electrochemical-sensors manufacturer, Analytical Technology (ATI). However, it also serves to highlight the importance of ensuring the reliable performance of all gas detection equipment.

Leading gas monitor manufacturer, Crowcon, recommend a simple 30-second bump test of your gas detector, which will help you identify problems and avoid potentially fatal accidents.

What is bump testing?
A bump test is a brief exposure, or ‘bump’, of the gas detector with a known concentration of the target gas or gases. It verifies that the sensor is responding, and the instrument is functioning properly. A simple bump test increases confidence in the detector and highlights any need for re-calibration.


Crowcon Tetra3 (T3) Gas Tester
Crowcon’s new Tetra3 (T3) GasTester provides a cost-effective, fast and simple solution for the Tetra:3 portable, multi-gas detector.

When inserted into the tester, the Crowcon T3 automatically switches into bump mode. Once the test is complete, the result is then accepted by the user and automatically logged in the Crowcon T3. A passed test reassures the user that their detector is in good working order, while a failed test will inform the user that their instrument needs to be re-calibrated or serviced.

The Crowcon T3 Gas Tester can bump sensor for flammable, oxygen, carbon monoxide, hydrogen sulphide and carbon dioxide gases. It is capable of testing up to four gases within just 60 seconds, as well as confirming that visual and audible alarms are working correctly. When used with a fixed flow regulator, the T3 Gas Tester provides approximately 100 bumps per 34 litres of quad gas, making it very cost-effective. As a lightweight, stand-alone unit, it is ideal for both on-site and in-field testing. Fast and simple to use, it features automatic gas detector recognition and automatic gas delivery. It can also be mounted to the wall, desk or attached to a DIN rail, without the need for a power supply.
