Cubic - Model SJH -Industrial Grade Infrared (NDIR) Methane (CH4) Gas Sensor

Miniature NDIR CH4 sensor SJH detect Methane（CH4）concentration from 0 to 100% based on NDIR technology which is superior than thermal catalysis and thermal conductivity technology.

It has advantages of convenient operation, accurate measurement, reliable operation, simultaneous output of voltage and serial port, and double beam design. It meets the different requirements of industrial field and laboratory measurement, and is widely used in gas detection and analysis in petrochemical, chemical, coal mine, medical and laboratory fields.
