The MiniBump is an ultra-small certified calibration gas instrument specifically designed for "bump" testing chlorine, hydrogen, hydrogen cyanide and hydrogen sulfide gas sensors.
The MiniBump cal gas generator uses only two "AA" alkaline batteries and easily fits inside your shirt pocket. Best of all, the MiniBump gas generator is extremely cost effective! The field replaceable electrochemical generating cell costs about as much as a disposable cylinder, but provides up to 1000 tests with no shelf life.
