GM35 In-Situ gas analyser

In-situ analyser for CO,CO2,H2O,N2O

Simultaneous or as individual measurement: the GM35 gas analyser measures CO2, H2O and CO, or N2O, as well temperature and pressure – and it does this reliably, quickly, and economically. As an in-situ gas analyser, the GM35 detects these gas components directly in the gas stream without gas sampling. Reliability, precision, and short response time of the GM35 offer a key advantage for efficient control loops in all CO and CO2-generating processes.
