More Information


The Model 9000MGA is a Series III microprocessor-based gas analyzer featuring gas filter correlation infrared measurement and a paramagnetic oxygen module. Up to three gases may be measured in a single 3 RU high standard Series III instrument case.
High and low concentration analyzers employ a unique dual length optical path for drift-free, linear operation.

We are excited about getting this product. We have fielded many questions in the past and turned away countless product inquiries for high accuracy, multigas applications. As far as we know, this is the only multigas GFC/IR gas analyzer available anywhere. This equipment can also be outfitted with a paramagnetic oxygen module.
Based on the proven, 7000FM Series GFC/IR and Model 8000M Paramagnetic oxygen gas analyzers, the 9000MGA is a much higher quality alternative to drifty single beam and fuel cell oxygen multigas analyzers that are currently available.
Save yourself the trouble and disappointment of buying something that won't work properly. The 9000MGA is available now:

The standard 3-rack unit tall, Series III instrument case will have up to three sets of keypads and operator displays on the front panel. Each channel may be operated seperately (as a seperate gas analyzer) and plumbing connections may be easily configured at the rear panel for this type of operation. This is a dry-basis measuring instrument so it must be used on a dry or conditioned gas stream. A series 200 gas conditioner or similar chiller will work without problems.

Applications for the 9000MGA include:

Environmental compliance
Combustion research
Process monitoring
Gas Turbine Emissions
Automotive Emissions
