SYSTEM AND METHOD FOR GAS REUSE IN TESTING OF HAZARDOUS GAS DETECTING INSTRUMENTS

Abstract:

Embodiments relate generally to a gas detector test fixture (102) that recycles test gas, which can then be reused. A portable gas detector test fixture (102), comprises a test chamber (104), a processor (134), a docking connector (132) communicatively coupled to the processor (134), an output device (138) communicatively coupled to the processor (134), a memory (136) communicatively coupled to the processor (134), and an application (137) stored in the memory (136) that, when executed by the processor (134), is configured to conduct a bump test on a portable gas detector (106) plugged into the docking connector (132) and to output the bump test result to the output device (138). The test fixture (102) further comprises an inflow line (124) configured to connect to a test gas supply line (120) of a test gas container (118), where the inflow line (124) is coupled to the test chamber (104), and an outflow line (130) configured to connect to a test gas return line (126) of the test gas container (118), where the outflow line (130) is coupled to the test chamber (104).
