FPI - Model GRD - 3000 -Explosion-Proof Hydrogen Analyzer
The GRD-3000 Explosion-proof Hydrogen Analyzer is designed to continuously measure the concentration of a single component of interest in a flowing gas mixture. The measurement is based on the different thermal conductivity of the individual components of the sample stream. It compares the thermal conductivity of a sample stream with that of a reference gas of know composition. The microprocessor-based GRD-3000 Explosion-proof Hydrogen Analyzer adopts thermal conductivity gas sensor with high performance, which features strong anti-interference capacity, high resolution and fast response, digital display, upper and lower alarm, standard signal output and relay contact alarm output. The analyzer consists of electronic control and thermal conductivity sensor, which is supplied in an explosion-proof enclosure suitable for installation in hazardous areas.
