2.1 Product description
The GM32 gas analyzer serves for continuous measurement of gas concentrations in
industrial plants.
GM32 is an in-situ measuring system which means measuring is done directly in the gas
carrying duct.
● Measuring components: SO

(device specific) as well as the reference
variables temperature and pressure.
● GM32-TRS-PExx version: TRS components.
(Only for kraft pulp mills. Only with GPP probe)
● Measuring principle: Differential Optical Absorption Spectroscopy (DOAS).
