NDIR Stack Gas Analyzer
All diatomic and polyatomic molecules have one or several vibrational modes which can absorb radiation and give rise to a unique absorption spectrum in the infrared region with several absorption lines. Taking any one of the IR absorption lines of the target gas as its finger print, an instrument can be built for measurement of target gas concentration. Infrared technique is endowed with very high specificity when a right choice of the vibrational frequency of the target molecule is made. This technique is cost effective and reliable for measurement of gas concentration in parts per million range.
The Uniphos NDIR Stack Gas Analyzer are endowed with specificity and have adequate sensitivity for the detection of gases like SO2, NOx, CO, CO2 and CH4 in industrial stacks. The in-built powerful pump enables the analyzer to draw the sample from stack. Analyzer is equipped with the latest embedded and IOT technologies which enables the user to perform Remote calibration. This PLC based analyser incorporates all desired features which makes it user-friendly and fail safe.
