Portable gas detector eases calibration testing

Crowcon has announced the launch of a new bump test gas spray to make calibration of portable gas detection equipment both quicker and easier.

A bump test, or functional test, involves exposing a detector to a gas concentration that exceeds the units alarm set points, testing the sensors ability to respond and making it an essential part of the UN safety directives.

The new system performs tests on handheld gas detectors, either on site or while mobile, using a 12l spray canister. The gas is applied through a straw on the canister nozzle and a small amount of gas is sprayed into a calibration cap placed over the sensor, removing the need to carry heavy gas bottles, regulators, docking stations and other equipment.

According to Crowcon, this new method makes the tests most cost-effective and easier to use when on the road.

Richard Dunn, portable product manager, Crowcon added: “The gas cans can be bought in a range of gases or combination of gases to suit. The kit comes with a canister of chosen gas, nozzle, straw and an MSDS sheet.”
