Understanding Combustible Sensor Performance

combustible sensor in a 100 percent gas or vapor environment will produce a reading of zero percent LEL. This is the reason that testing protocols for evaluating confined spaces specify measuring oxygen first and then combustible gases and vapors. For this reason confined space instruments that contain catalyticbead sensors should also include a sensor for measuring oxygen. If the instrument ...
