Industrial Grade NDIR CH4 Sensor-SJH

Industrial Grade NDIR CH4 Sensor-SJHSJH

The miniature NDIR CH4 sensor SJH is based on NDIR technology that is superior to thermal catalysis and heat conduction technology, and can detect 0 to 100% methane (CH4) concentration. It has the advantages of convenient operation, accurate measurement, reliable operation, simultaneous output of voltage and serial port, and dual beam design. To meet the different requirements of industrial field and laboratory measurement, it is widely used in gas detection and analysis in petrochemical, chemical, coal, medical, laboratory and other fields.
