LEL vs PID Sensors
LEL vs. PID Sensors
- Catalytic LEL and PID sensors are complementary detection techniques
- Catalytic LEL sensors excellent for methane, propane, and other common combustible gases that are NOT detectable by PID
- PIDs detect large VOC and hydrocarbon molecules that are undetectable by hotbead sensors
- Best approach is to use multi-sensor instrument that includes both types of sensors
