The Microsense IR Nitrous Oxide Gas Detector

The Microsense IR is a high quality infrared fixed gas detector for detection of Nitrous Oxide (N2O) that meets the requirements for economic and reliable monitoring of gas levels in a wide range of environments and applications.

Housed within an IP54 rugged enclosure, the Microsense IR Nitrous Oxide detector is suitable for use in non-hazardous areas. The instrument utilises an optical NDIR gas sensor which features excellent repeatability, stability and long lifetime. The NDIR sensor has no need for any compensation algorithms that are used in more simple sensors to compensate for their drift. The unit is available in various detection ranges and can be used in either standard diffusion model or as suction type detection, thanks to its internal sampling pump.

The unit offers easy access for installation of field wiring and cable entry from back of its enclosure. All sensors are temperature compensated, which results in enhanced stability compared to similar products available on the market.
