Industrial Grade Low Power NDIR Methane SensorSJH Series

The miniature methane sensor SJH series is based on NDIR technology with dual beam design, that is superior to semiconductor and catalytic technology, and can detect 0 to 100% methane (CH4) concentration. Through component optimization, dynamic working mechanism, also smart algorithm etc. , SJH can achieve average working current 1mA. It has the advantages of accurate measurement, simultaneous output of voltage and serial port, convenient operation and long life span more than 10 years. It can be widely used in portable gas detectors, wearable devices and IOT solutions etc.
