Product Information
IRM-AT Infrared Methane (CH4) Sensor Thermopile Detector Description
Alphasense CO2 and Methane infrared sensors are supplied in the industry standard miniature (20mm diameter) gas sensor housing.
Patented optics give the best signal to noise ratio of any 20mm diameter NDIR and universal linearisation constants allow easy implementation.
The on-board temperature sensor allows for software compensation, including ideal gas law correction.
Methane/ Hydrocarbons
The IRM-AT uses a dual thermopile detector for measuring Methane and other Hydrocarbons in non-explosive environments. The plastic housing limits use to non-Ex environments up to 2.5% Methane.
