IRNET-P 20mm

ATEX certified NDIR sensor for CO2 or HC detection


The IR series of infrared gas detection sensors use the technique of NDIR (Non Dispersive Infrared) to monitor the presence of hydrocarbons or carbon dioxide.
This technique is based on the fact that the gas has an unique and well defined light absorption curve in the infrared spectrum that can be used to identify the specific gas. The gas concentration can be determined by using a suitable infrared source and analysing the quantity of energy absorbed from the gas inside the optical path.

IRNET-P is now SIL2 approved
