FAQ - Methane Sensor

What is methane sensor?

A methane sensor is a device that measures the concentration of methane in the environment, usually with an alarm function. Once the concentration exceeds the limit, it will alarm.

What type of sensor is used to detect methane gas?

According to different use environments, there are usually three types: wall-mounted methane sensor, portable methane detector, and fixed methane detector.

How to calibrate the methane sensor?

Our methane sensor has been calibrated before leaving the factory and can be used directly after installation without secondary calibration.
