Infrared CH4 gas sensor

Infrared CH4 gas sensor is a methane gas sensor module using (NDIR) non-dispersed infrared technology. Built-in temperature sensor for temperature compensation. The advanced optical path, precision circuit and intelligent software are combined to form a universal NDIR methane gas sensor. The infrared CH4 gas sensor has good selectivity, high sensitivity, no oxygen dependence, long life and low power consumption.

Infrared CH4 gas sensor Features

1. Large range monitoring

The good selectivity of the product makes up for the shortcomings of traditional electrochemical sensors in the selection of high range test range.

2, not afraid of harsh environment

Using imported infrared light source and double channel pyroelectric measurement, and can automatically carry out temperature compensation function, even in the harsh temperature and environmental conditions, can also get stable and reliable measurement results. High temperature resistance (80°C), suitable for coal mine, oil field, chemical industry and other types of flue gas environment.

3. No significant life time limit

NDIR gas sensor has no obvious consumption compared with traditional electrochemical sensor. The electrolyte on the sensor will not be depleted due to long-term exposure to target gas or interference gas crossing, and the service life is long.
