Infrared Methane (CH4) Gas Sensor

Model Number
Gascard NG CH4


Standard Lead Time
2-4 weeks

The Gascard NG works on the principle of infrared absorption of the target gas methane. The measurements are automatically compensated in real-time for changes in temperature and atmospheric pressure.

These sensors are designed to be easily integrated into OEM systems or quickly implemented into prototyping, production, or automation control systems.

The Gascard outputs data via voltage or current analog signals and digital RS232.
