In Situ Analyzers - GM 31 Family

The GM 31, SICK's newest, fully EPA-compliant, onsite measurement system, helps you make sense of the information available in flue gases, exhaust gases and technical gas/solid mixtures. The GM 31 makes it easy for operators of power utilities, incinerators and chemical industries to continuously check processes and monitor pollutant emissions.

The GM 31 onsite gas measurement system consists of a transceiver, a probe projecting into the gas stream that measures across an 800 mm-wide gas column and an air-purging unit that protects the optical surfaces from dirt and overheating. The transceiver and probe can be mounted in the chimney or duct with a single attachment point bracket. The gases are identified by evaluating the light emitted and the light received by the transceiver. The optical wavelength and light absorption for each component of a gas differ, making it possible to determine precise concentrations of sulfur dioxide (SO₂), nitrogen monoxide (NO), ammonia (NH₃) or nitrogen dioxide (NO₂).

The controls of the GM 31 gas measurement system can be located up to 1200 m away from the measuring site. The user-friendly MEPA software allows range or limit values and other system parameters to be set from the control center via an RS 422 interface. An RS 232 interface is provided for onsite service and support. Remote diagnosis and maintenance of the GM 31 are also possible via modem, making the GM 31 convenient in both operation and maintenance.

A variety of other analyzers are also available with different features for different applications.
