FTIR Process Gas Analyzer
The Gasmet FCX-Series features a comprehensive range of high performance FTIR process gas analyzers. The wall mounted Gasmet FCX process gas analyzers offer reliable results even when analyzing complex gas mixtures.
The Gasmet FCX process gas analyzers incorporates a Fourier Transform Infrared spectrometer, gas cell, and signal processing electronics, a built-in Industrial Computer and a TFT display into a compact enclosure.
The analysis results of Gasmet FCX process gas analyzer are transmitted via 4-20 mA analog output signals or digital outputs (ModBus)
The enclosure has IP 65 protection and the analyser is equipped with Vortex cooling system.
The sample cell can be equipped with an optional heating and temperature control up to 180 °C. Sample cell absorption path length is selected according to the application.
