022_CACGas_BTS-HP New Casing-257206-edited.jpgAfter 30+ years in the gas detection business, I am still surprised at the number of gas detection users not bump testing their instruments prior to use.   

Whatever the term….bump test, challenge test, function test, response test or verification. The only way to guarantee that a gas detection instruments will detect gas is to test it with a known concentration of gas.  Exposing the instrument to a known concentration of test gas will show whether the sensors respond and whether the instrument functions properly.
