In-situ gas analyzers GM35

Overview

For efficient control of combustion and drying processes

Simultaneous or as individual measurement: the GM35 gas analyzer measures CO2, H2O and CO, as well temperature and pressure – and it does this reliably, quickly, and economically. As an in-situ gas analyzer, the GM35 detects these gas components directly in the gas stream without gas sampling. Reliability, accuracy, and short response time of the GM35 offer a key advantage for efficient control loops in CO and CO2-generating processes.

At a glance

Dynamic humidity correction
Fast in-situ measurement directly in the process
Simultaneous determination of up to three gas components, temperature, and pressure
No gas sampling and conditioning
