Industrial Grade Low Power NDIR Methane Sensor SJH-100A-LSJH-100A-L

The miniature methane sensor SJH-100A-L is based on NDIR technology with dual beam design, which is superior to semiconductor and catalytic technology, and can detect 0~100%Vol methane (CH4) concentration.

It has the advantages of low power consumption, accurate measurement, convenient operation, long lifespan, etc.

With a low power IR source, SJH-100A-L can achieve average current consumption 16mA which make the sensor suitable for battery or solar powered IoT device. It's an energy-efficient, reliable and accurate solution for industrial application.
