Why Is Methane Used as A Calibration Gas? | Newcastle ...

2020-06-22· This may be because the sensors are essentially “poisoned” and cannot pick up on the levels of Methane. There are many reasons an LEL sensor with a degraded catalyst would respond to Pentane during calibration and bump testing, yet might not respond to Methane. The detectors can essentially become blind to Methane and possibly other high ignition temperature gases, including …
