The Infrared Methane CH4 Gas Sensor (CU-1000) is a 0-5% GasLab exclusive power management capable sensor.

This combustible NDIR Sensor has a power management feature which enables you to stop the sensor measuring activity via the software, making an invaluable means for portable and handheld operations.

The sensor can be reliable for the detection of Refrigerants, such as R32 as well as other hydrocarbons like propane gases. The CU-1000 is also directly compatible with the GasLab software via UART interface of Gasbox. 

The CU-1000 can be used for environmental monitoring, gas drainage, chemical, petroleum, metallurgy, oil depots, liquefied gas stations, paint, gas transmission, and other combustible gases.
