GFCIR gas analyzer

Gas Filter Correlation Series 7000FM

The Series 7000FM relies on the Gas Filter Correlation technique of the NDIR gas measurement principle.

This IR gas analyzer also features a solid state detector and long life IR source.


The compact Series 7000M GFC-IR Gas Analyzers
are designed for the continuous monitoring of CO, CO2, SO2 and other infrared absorbing gases for research and compliance gas monitoring in industrial and automotive applications.

The gas analyzer has a totally automatic microprocessor-based operation including auto-startup, auto-calibration, auto-range, internal parameter monitoring and alarms. This makes the instrument ideal as a "smart" stand-alone unit or as a "building block" for systems integration via a RS-232 communications port or remote contact closures. Automatic diagnostics and fully-configurable concentration alarms are also integral to the series 7000FM gas analyzers.

A large multifunction, backlit LCD provides a clear display of carbon monoxide, carbon dioxide or sulfur dioxide gas concentration measurement, range, sample flowrate and the status of critical operating parameters including sample flow, pressure, temperature, DC and bias power supplies. The intuitive, menu-driven interface and soft key buttons enable the operator to quickly configure and control the gas analyzer function. The unit features 19" rack mounting at 3 RU height and a weight of 50 Lb. It has a dual voltage capability of 115 Vac and 230 Vac which is switchable from the rear panel.

A paramagnetic oxygen measurement may be added within the analyzer.

Model versions are available for low sample flow, response time and extended low range sensitivity. Please condult us for your specific application requirements.
