Crowcon announces new portable gas bump tester for remote testing of personal gas detectors

05 December 2014

Crowcon, the gas detection specialist, has today announced the availability of a new portable gas solution for bump testing. The new method eliminates the need to carry around cumbersome gas bottles and docking stations or return to base to test handheld gas detectors.

Resulting from an innovative reapplication of existing technology, the Crowcon Bump Test Gas Spray performs bump tests on handheld gas detectors, either on site or on-the-road, using a 12 litre spray canister. The gas is simply applied through a straw on the canister nozzle and a small amount of gas is sprayed into a calibration cap placed over the sensor.

“Having a fully portable 12 litre spray can and straw is just the ticket to test and calibrate on site. It could not be easier,” stated Richard Dunn, Portable Product Manager, Crowcon. “With no regulator, no heavy gas bottle and no docking station, it’s a no brainer for bump testing.”

Traditionally, to conduct a bump test, an engineer would require heavy gas bottles, regulators, docking stations and other associated paraphernalia, but for most, this really is not an option. Engineers on-the-road have been asking for something to address this challenge.

“We have listened to our customer concerns and found a novel way to satisfy their requirements,” Richard Dunn 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.”

Crowcon is offering this solution as the most cost-effective and easiest way to bump test when mobile. Less equipment means less weight to carry and more room for storing productive equipment. Spray canisters are also covered by less demanding regulation (directives UN1950), helping keep costs down further.
