WA154 Mk 4 CAS System

The WA154 Mk 4 Combustion Analysis System (CAS) has been designed to continuously sample and measure the levels of Carbon Monoxide and Carbon Dioxide in combustion exhaust.

There is also an option for NO,NO2 and NOx using our 4000VM Heated Vacuum CLD NOx Analyser.

The system is self contained and housed in a free standing mobile cabinet. It includes a single Model 9000MGA CO/CO2 gas filter correlation infrared analyser and a water removal sample handling system.

The results of the measurements and the ratio of CO to CO2 are shown on calibrated displays.
