1.1 FUNDAMENTALS
Gas flow
A built-in sampling pump is drawing the flue gas through the gas-sampling probe into the
analyzer.
1. The gas flows through the gas-sampling probe to the condensation trap.
2. Then the gas passes through a particle filter where dust particles are removed.
3. Then the gas enters the sensor chamber.
Gas temperature
The gas temperature is measured by a thermocouple located at the tip of the gas-sampling
probe.
Electrochemical sensors
Each electrochemical sensor measures the concentration of a specific gas.
Electrochemical sensors can be damaged
-
if exposed to small particles
- never measure without a dust filter
-
if water / condensation comes in contact with the sensors -
empty condensation
trap
Service / Calibration
A “Service” message will be displayed after 1000 hours or after one year of operating time.
IMR Environmental Equipment, Inc. recommends checking the calibration once a year.

When not in use or in storage, please make sure to keep the analyzer plugged into a wall outlet
(AC).
This ensures that the analyzer maintains a constant battery charge and function properly if
needed.
Prolonged periods of disuse without charging the battery may result in a weak battery and the
battery can lose its ability to hold the charge.
