IMR 2800A-IR Flue Gas Analyzer

The IMR 2800A-IR is a portable Flue Gas Analyzer for industrial applications.
The rugged combustion analyzer can be equipped with up to 8 sensors.
Its basic unit has an O2 Oxygen sensor , a CO Carbon Monoxide sensor, a NO Nitric Oxide sensor and a SO2 Sulfur Dioxide Sensor. The other sensors are customer select-able as well as the measuring ranges.
The IMR 2800A-IR measures and calculates all the needed parameters to perform a thorough emission test.


The IMR 2800A-IR is a portable, continuous measuring flue gas analysis instrument housed in an aluminum case.

It measures flue gas  temperature, air  temperature, Oxygen O2, Carbon monoxide CO, Nitric  Oxide NO and Sulfur Dioxide SO2.

It can optionally measure Nitrogen Dioxide NO2, Sulfur Dioxide SO2, Hydrogen Sulfide and Hydrocarbons HC and much more.

Combustible calculations like Losses, Excess Air and Carbon dioxide CO2 are standard as well as the measurements for Draft and optionally Soot.
