Clairair's infrared gas sensors incorporate patented technology to produce an optical gas sensor within an industry standard format. Standard non dispersive infrared gas sensors are complemented by a state of the art OEM 4-20mA transmitter that controls the sensor, provides a  robust linear 4-20mA output and incorporates an extensive serial communications facility. Infrared sensors with support electronics are easily configurable to a wide range of applications. Patented sensors currently cover %lel hydrocarbons, ppm and low %volume carbon dioxide and high %volume carbon dioxide. Find Out More

Catalytic gas sensors (alternatively known as "Pellistors" from the original description as a "Pelletised resistor") are well known combustible gas sensors that monitor the presence of explosive levels of most combustible gases, inclusing those that are not detectable by normal infrared means. Hydrogen is a classic example of an explosive gas that is not infrared active. Find Out More
