With a spectral response from 1 – 5.2µm these high detectivity detectors are ideal for non-dispersive infrared (NDIR) simultaneous gas sensing. Popular gases include CO2, CO, HC and a reference channel typically at 4µm.
For increased signal to noise, thermal electric coolers (TECs) with one, two, three or even four stages can also be included.
Due to their high response speed, typically exhibiting a 200µs time constant, these detectors are ideal for fast events, such as the detection of hot spots in train wheels, car engine combustion efficiency, electro-mechanical converters, and incinerator efficiency for example.
