SICK GM901 Gas Analyser – Carbon Monoxide (CO) Gas Measurement & Emissions Monitoring
SICK GM901 In-Situ Gas Analyser
In-Situ Gas Analysers
SICK GM901
The SICK GM901 in-situ gas analyser provides efficient process analysis, detection and measurement of carbon monoxide (CO) gas. It is available as either a cross-duct or probe type version. making SICK GM901 gas analysers well suited for difficult carbon monoxide (CO) gas measuring tasks such as high pressure, critical flow profiles, or high measuring gas concentrations.
GM901 in-situ gas analysers are ideal for applications such as; the optimisation of all kinds of combustion processes or biomass combustion plants, CO monitoring in coal mills, process monitoring in the food industry, control of small boiler facilities, and during roasting processes.
