Extractive gas analyzers
GMS800 FIDOR

Your Benefits

Very high availability
Convenient remote diagnosis and operation via Ethernet using SOPAS-ET software
Very low maintenance costs due to the absence of moving parts
Replacement of complete assemblies and modules makes repairs easy
Compatible with predecessor systems
Hydrogen as fuel gas, expensive helium is not required
Low operating costs, e.g., due to low hydrogen consumption
The GMS811 FIDOR version, on which the BCU control unit can be separated from the analyzer unit, supports convenient control and monitoring from a central control room

The exact device specifications and performance data of the product may deviate from the information provided here, and depend on the application in which the product is being used and the relevant customer specifications.

Overview

The GMS800 FIDOR extractive gas analyzer of the GMS800 analyzer family is ideally suited for emission measurements according to regulatory requirements (in waste incineration plants, cement and/or power plants, for example). Based on the proven flame ionization detection principle, the GMS800 FIDOR measures total hydrocarbon concentrations in gases at both trace levels and high concentration levels. The GMS800 FIDOR is available in three types: the GMS810 FIDOR with integrated BCU control unit, the GMS811 FIDOR with separate BCU control unit, and the GMS840 FIDOR in a space-saving wall housing. The housing makes stand-alone operation and integration into existing systems such as the MCS200HW multi-component analyzer from SICK very easy.
