This analyser is meant to be used for ambient air measurements in applications such as industrial air quality monitoring and occupational health measurements. The key features of the Gasmet Cx-4015 include for example a high sensitivity sample cell for lowest possible detection limits.
All analyser products are based on in-house developed and patent protected FTIR technology. Products have also received TÜV (17 BlmSchV,Germany) and MCERTS (UK) product certificates.
Quality without compromise
Multicomponent FTIR Gas Analyzer
GASMET ON-LINE SERIES includes multicomponent gas analyzers for continuous monitoring applications. The GASMET Cx-4015 incorporates a Fourier Transform Infrared spectrometer, a temperature controlled sample cell, and signal processing electronics. The analyzer is fully equipped for fixed installations and it offers versatility and high performance for all industrial users. The GASMET Cx-4015 is designed workplace air monitoring, and quality control applications. It is an ideal tool to measure components of interest in ambient conditions. The sample cell can be heated up to 50 °C. Sample cell absorption path length is selected according to the application. The GASMET Cx-4015 allows simple calibration using only single component calibration gases. The user can easily configure the analyzer for a new set of compounds.
