Bump Test Kits

Gas Monitor Bump Test Kits

CAL Services can supply you with bump test kits which include the specific gas mixture recommended by your gas monitors manufacturer as well as a pressure valve and replacement sensor clip cover.

Gas monitors need regular calibration and bump testing if you want to be sure they are working properly. As everyone who owns a gas monitor knows – whether it’s a multi-gas monitor like the GasAlert Micro Clip XL, or a single-gas monitor like the Gas Clip H2S Monitor – a quick bump test before using it to protect your life is an excellent, and highly recommended idea.

Bump testing is the process that verifies that the gas detector’s sensors properly respond to the units target gas. For example, during a bump test a H2S sensor is exposed to a known quantity of H2S gas in order to make sure it responds by going into alarm.

Why is this so important?

You are not testing to see if your gas monitor accurately displays quantities of target gas, but that it picks up on the presence of the gas in the first place.

The necessity of bump testing is vital due to the fact, in part, that portable gas detectors are subject to a certain level of abuse; they are usually worn on belts or clipped to clothing and may get dropped or knocked during the typical working day. They may also be exposed to rain, dust, oil or sealants and the sensor’s protective membrane may become blocked.

Bump testing the sensors is important and easy. The basic concept is to expose the sensors to the target gas so you know for sure the monitor will go into alarm if it happens in the field. Your gas monitor will come with a sensor clip and a bit of clear hose that you’ll secure over the sensor plate. Attach the other end of the hose to your calibration gas and regulator. Turn the monitor on and let it boot up. Then open your regulator and allow gas to flow until the monitor goes into alarm.
