The Chillcard NG range of nondispersive infrared gas sensors from Edinburgh Sensors has been extended to include two new gases: carbon monoxide (CO) and carbon dioxide (CO2).
Standard sensors for these gases use a miniature lamp with a tungsten filament as the source of infrared light.
However, in applications such as endothermic gas annealing furnaces and gasification, where high levels of hydrogen (H2) are present, the lamp can have a reduced lifetime.
Chillcard NG sensors are built with a micro-machined thermal infrared emitter that has a longer lifetime in these challenging environments, says the company, giving less downtime and reduced long-term cost of ownership.
The range of gas sensor instruments also includes high accuracy sensors for the detection and measurement of R-125 and R-134a refrigerant gases, where detection levels of 0-3000ppm by volume are required.
