The Dr. Födisch MGA 20 is a cold gas analyser for measurement of pollutants in flue gas and for process control using IR-technology. A high-precision infrared photometer is used to determine the concentration of up to 8 gas components by means of infrared absorption.
The analyser MGA 20 includes a high precision optical bench (infrared photometer) consisting mainly of an IR light source with chopper wheel, a measuring cell, a motor driven filter wheel and a detector.
