Abstract
Embodiments relate generally to a gas detector test fixture that recycles test gas. A portable gas detector test fixture, comprises a test chamber, a processor, a docking connector communicatively coupled to the processor, an output device communicatively coupled to the processor, a memory communicatively coupled to the processor, and an application stored in the memory that, when executed by the processor, is configured to conduct a bump test on a portable gas detector plugged into the docking connector and to output the bump test result to the output device. The test fixture further comprises an inflow line configured to connect to a test gas supply line of a test gas container, where the inflow line is coupled to the test chamber, and an outflow line configured to connect to a test gas return line of the test gas container, where the outflow line is coupled to the test chamber.
