The Measuring principle:
Gas analysis based on NDIR technique is an established method to determine the concentrations of gases in complex mixtures. Our sensor uses novel optical components for optimum analysis results. For the combined detection of CO and NO a multi wavelength detector is implemented. The Analyser AMS 2500 is developed for the determination of different concentrations of CO, CO2 and NO.
The Analyser AMS 2500 consists of an electronic, the pneumatic components for the gas supply and flow control, installed in an electronic housing 84 TE / 3 HE. To protect the analyser against high gas pressure and fluctuations, the analyser can be equipped with a pressure reducer for gas pressure up to 10 bar (abs) and a manual purge valve. A micro processor controls the electronics and the display. Calibration and service are menu-driven.
