IRNEX-P Low Power

NDIR gas sensor for CO2, methane, propane and other hydrocarbons 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.

The IRNEX-P Low Power sensor is equipped with electronics and firmware in order to provide an output that is linearized and temperature compensated and is suited for manufacturers also without any specialist knowledge in IR technology. The output is analogue voltage type [0.4 V—2 V] dc (other voltages are available on request).
