In-situ gas analyzers
GM901
Overview
The GM901 gas analyzer is available as a cross-duct or probe type. As a result, it is suited to a broad range of applications – even for difficult measuring tasks such as high dust loads, overpressure, critical flow profiles, or high measuring gas concentrations.
At a glance
- Representative measurement along the duct diameter
- Operation via control unit
- Short response times
- Verifiable with gas-filled cell; gas-testable probe with test gas
