Gasmet On-line Series includes multicomponent gas analyzers for continuous monitoring applications. The Gasmet CX4015 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 CX4015 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 CX4015 allows simple calibration using only single component calibration gases. The user can easily configure the analyzer for a new set of compounds.

Gasmet CX4015 can be integral part of Gasmet Continuous emissions monitoring system (CEMS II) or it can be operated as an individual analyzer.

AREAS OF APPLICATION : Occupational hygiene, Quality control.
