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.

Operating Temperature

50oF..104oF / 10oC..40oC
If the unit is brought in from the cold, then it should be allowed to warm up for a few minutes.

Storage Procedures: IMPORTANT!

Storage Temperature

-4oF..122oF / -2oC..50oC
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.

2.4 SYSTEM CONNECTIONS

2.4.1 Probe

The gas-sampling probe plug and hose has to be connected to the analyzer before it can be
turned on and must stay connected during the whole measurement.
If the gas-sampling probe is not connected, then the analyzer cannot perform an accurate
calibration and an error message will be displayed.

Type S (if equipped with soot measurement)

The probe S has two hoses. One for the flue gas measurement and one for the draft
measurement. Both hoses must be connected to their fittings at all time.
It also has a connection line to connect the thermocouple with the analyzer.

a) Thermocouple - Connect the thermocouple plug (5-pos) with the
'flue gas temp' socket of the analyzer

b) Flue gas - Connect the hose, which has the condensation trap
inline to the barbed fitting 'gas input'

c) Draft - Connect the second hose to the barbed fitting
'draft'

Type E

The probe E has one hose for the flue gas measurement and the draft measurement.
It also has a connection line to connect the thermocouple with the analyzer.

a) Thermocouple - Connect the thermocouple plug (5-pos) with the
'flue gas temp' socket of the analyzer

b) Flue gas - Connect the hose to the barbed fitting 'gas input'

The hose must be connected to the 'gas input' fitting for the flue gas measurement.
The hose must be connected to the 'draft' fitting only for the draft measurement and it must be
connected back to the 'gas input' fitting after the draft measurement is completed.

Type C (if equipped)

The probe C is a ceramic probe with a Pt-RhPt thermocouple and it is used for high
temperatures. The temperature range is 302F-2732F / 150C-1500C.
It has the same connections as the probe E.

2.4.2 Ambient air temperature plug

The ambient air temperature plug must be connected to the instrument at all time.
If the ambient air temperature plug is not connected, then the unit shows an error message.

The ambient air temperature plug measures the temperature of the air that is used for the
combustion process.
The measured temperature is needed for various calculations.

Connect the plug (4-pos) with the 'air temp' socket of the analyzer.

2.4.3 Gas fitting

The gas hose of the gas-sampling probe must be connected to the gas fitting.

2.4.4 Draft fitting

The draft hose of the gas-sampling probe must be connected to the draft fitting.

2.4.5 LED

The LED shows the power status of the unit.
RED: battery powered
GREEN: AC connected and turned off (charging the battery)
YELLOW: AC connected and turned on

2.4.6 Differential pressure fitting (if equipped)

The analyzer is equipped with a third barbed fitting for a differential pressure measurement.
The differential pressure is the pressure that is measured between the 'draft' fitting and this 3rd
fitting.
Connect a hose to this fitting and insert it into the medium and start the regular draft
measurement. The draft measurement measures now the differential pressure from the
medium to the flue gas, where the gas-sampling probe is inserted.

2.4.7 RS232 interface

The RS232 serial interface can be used to transfer data from the analyzer to a PC.
Real time data or stored data can be transferred (ASCII signs are getting transferred).
The serial connection to a PC must be a 'Null-modem connection'.
The IMR 2800 has a 9-pos. female D-Sub connector on the front panel.

2.5 POWER

The IMR 2800 works on 230VAC/50Hz or 110VAC/60Hz. A fuse selector next to the AC
inlet sets the voltage.

The analyzer is able to work without being connected to the AC by using the power of the
internal rechargeable battery lead acid battery.

However IMR recommends connecting the analyzer always to the AC during a measurement
or during storage.
