A high-precision infrared photometer is used to determine the concentration of up to 8 gas
components by means of infrared absorption.
Furthermore, an electrochemical cell, zirconium dioxide sensors
or paramagnetic sensor can be congured for oxygen measurement.
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 motordriven lter wheel and a detector
