An NDIR gas analyzer consists of an electrically or mechanically modulated infrared source, a gas cell and usually a pyroelectric DETECTOR. An electronic DEVICE calculates the gas concentration based on signal voltage. InfraTec offers a large number of standard IR narrow bandpass filters (NBP), which are optimally matched to the absorption properties of the gases to be measured. The filters are mounted in the cap of the detector, which is welded to the detector base body. With multiple gases to be measured, the use of multi-channel detectors is RECOMMENDED.
