GFCIR gas analyzer

2 & 3 Gas Analyzer Series MGA9000

The Series MGA9000 relies on the Gas Filter Correlation technique of the NDIR gas measurement principle coupled with a highly accurate Paramagnetic Oxygen sensor.

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



Using an inovative dual gas filter correlation infrared for accuracy without cross interference, paramagnetic for O2, individual gas inputs, displays, outputs and ranges, the MGA9000 offers cost-effectiveness and performance.

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 MGA9000 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.




The 9000MGA will drastically reduce the cabinet space required for a CEMS.
