1 GENERAL DESCRIPTION

The 2000 series is designed to satisfy the market needs; and it is the result of the advanced research and experience of
Eurotron. Eurotron has been developing and manufacturing portable flue gas analyzers since 1986.
EcoLine 2000, GreenLine 2000, BTU 2000+ and Unigas 2000+ are multigas compact hand-held multifunction

instruments. The micro-processor based instrument includes a flue gas analyzer, and an ambient parameters indicator.
Two internal electrochemical sensors read the Oxygen (O

2

) and carbonic monoxide (CO) gas concentration. The gas
temperature and air temperature are used in connection with the gas analysis to calculate the efficiency, excess air, and
CO2 concentration. A 10 gas parameters programmable table is used for calculations approved in accordance with
DIN33962.
External sensors are available for auxiliary measurements: ambient CO concentration (for operator’s safety), gas
network leakage procedure (pressure decay method) and natural gas leakage detector (sniffer).

The analyzers are completed with a differential pressure (draft) sensor, an internal printer, an internal memory for storing
data and a RS232 serial interface for configuration and data transfer from and to a PC.

♦ Draft measurement is possible using the internal pressure sensor and the Eurotron special gas sample probe.
♦ The optional internal printer is impact type and the generated document is very legible and has a long shelf life.
♦ The internal standard memory may store up to 250 complete gas analysis divided by Tag.
♦ The instruments have a standard IR serial interface for external HP 82240B thermal wireless printer.
♦ The optional RS232 cable and a configuration PC software are available to configure the analyzers.

3.1 Measurement Principle

The gas is sampled and aspirated through the probe with a primary pump powered at constant voltage.
To position the sampling probe in the exhaust gas pathway a hole of 11mm, up to 16mm, should be drilled and the
retaining cone of the sampling probe firmly screwed in it.

The retaining screw in the cone enables the probe to be easily moved to locate the core flow, normally
correspondent to the centre of the section of the chimney. The flue gas and exhaust gas pathway, should be

checked for gas-tightness before carrying out a measurement and, if necessary, non gas-tight points should be sealed.
The O

2

sensor is essentially an electrochemical cell, with two electrodes and electrolyte solution. The behaviour is similar

to a normal battery and therefore the sensitivity decreases with time.
The electrochemical cell grants accurate results for time intervals of approximately 60 minutes. The zero drift is
automatically corrected by the instrument every time is switched-on, using fresh ambient air as reference. This operation
should be made with the sampling probe not inserted in the chimney or with the sampling probe pneumatic connector
disconnected from the analyser gas inlet.
When a long time analysis has to be made, a new autozero procedure should be performed.
Measured and calculated parameters are indicated on a LCD alphanumeric display (40x56 mm), equipped with a
automatic back light device for easy readings, especially in poorly lit conditions.

3.1.1 Gas Sampling Probe

The sampling probe consists of a steel tube and a handle of thermoinsulating material. A positioning cone allows the
user to place the probe in holes with a diameter from 11 to 16 mm.
The gas temperature is acquired using a thermocouple type K with the junction placed on the tip of the probe.

3.1.2 Water Trap & Line Filter

The gas flows through an external combined water trap and line filter to avoid the presence of condensation and
suspended solid particles in the analysis section of the instrument. A cylinder is positioned at 15 cm from the instrument
gas inlet it is divided into two parts: the water trap and the line filter.

Instruction Manual MM850404 ed.05

15

The water trap works using the expansion principle: the gas flow decreases its speed inside the cylinder and it will cool;
the humidity will condense and the solid particles fall down. The section of the water trap must be periodically drained off
to avoid water from entering the analysis section. Pull the rubber plug (cat. EE650081) and slowly shake the trap to drain
the water. Push the rubber plug back to close the trap hole.

The line filter is positionned after the water trap and before the electrochemical cell. Its function is to stop the smallest
solid particles before the analysis. Remember to change the filter (cat. EE650074) every time it is dirty.

WARNING

THE WATER TRAP MUST BE KEPT IN VERTICAL POSITION DURING GAS SAMPLING. AN INCORRECT POSITIONING OF THE TRAP CAN

ALLOW THE WATER TO ENTER INSIDE THE ANALIZER AND DAMAGE THE ELECTROCHEMICAL SENSORS.

NEVER MAKE ANY ANALYSIS WITHOUT THE DRAINING RUBBER PLUG. THE MEASUREMENTS WILL BE INCORRECT.

WHEN YOU FINISH THE ANALYSIS, REMEMBER TO DRAIN THE WATER TRAP. BEFORE PUTTING THE GAS PROBE IN THE CARRYING CASE,

REMOVE THE CONDENSATE WATER FROM THE PROBE HOSE.

THE LINE FILTER SHOULD BE REPLACED WHEN DIRTY. NEVER MAKE ANY ANALYSIS WITHOUT LINE FILTER AND/OR WATER TRAP, AS IT

CAUSES AN IRREVERSIBLE DAMAGE TO THE ELECTROCHEMICAL SENSOR.

3.1.3 Gas Sensors

The analyzer uses long life sensors for O2 and CO measurements. The gas sensors are electrochemical cells composed
by two electrodes (anode and cathode) and an electrolyte solution. The sampled gas goes trough a selective diffusion
membrane. The oxidation process produces an output electrical signal proportional to the gas concentration. The signal
is evaluated by the electronics, converted to digital, processed by the microprocessor, displayed and printed with a 0.1%
volume resolution.
The flue gas must not be at a pressure that could damage or destroy the sensor. Measurements are always carried out
under "pressureless" conditions. The maximum permissible excess/reduced pressure is ±100 mbar.

Each sensor has a different response time:

O

2

=

20s to 90% of reading

CO (H

2

comp.) = 50s to 90% of reading

N

OTE: TO OBTAIN AN ACCURATE MEASURE IT IS RECOMMENDED TO WAIT 3-5 MINUTES.

If an excessive (>150% of F.S.) gas concentration is applied to toxic gas sensor, then an ±2% drift and a long resuming
time can be present. In that case it is recommended to wait for a measured value lower than 20ppm, by pulling fresh air
before turning the analyzer off.
Four acoustic and visual alarm levels can be set on four programmable parameters.

3.2 Auxiliary Measurements

3.2.1 Temperature Measurements

The instrument is equipped with two temperature inputs to measure exhaust gas and the burner air input temperatures
(combustion gas).

♦ A thermocouple type K (nickel-nickel chromium) is included in the tip of the gas sampling probe to measure the flue

gas/exhaust gas temperature. This thermocouple is suitable for permanent measurements at temperatures up to

800°C and for short-term measurements up to same time and location. Temperature measurement and gas
sampling from the flue gas pathway are thus always performed at the same site. The probe is connected to the unit
with compensated cable and connector. An internal Pt100 resistance thermometer is used for cold junction
compensation.

♦ A remote Pt100 sensor, can be supplied on request with a 2 meter cable to measure the air inlet temperature in

forced air boiler. This option is very important for an accurate efficiency calculation.

3.2.2 Pressure and Draft

The analyzer is equipped with a temperature compensated pressure sensor to measure the stack draft or pressure. The
pressure/draught sensor is based on the principle of the extension metric measuring bridge. The pressure range is -10 to
100mbar. The sensor is factory calibrated and does not require manual adjustment.
The zero drift, caused by ambient air temperature variation, is automatically cancelled at each instrument start-up. In
addition, for more accurate readings the operator can reset, using the pertinent key, the zero if required. Leave open the
“ΔP” connector during this phase.

N

OTE: FOR HIGHER ACCURACY, WE SUGGEST TO EXECUTE THE AUTOZERO PROCEDURE BEFORE PERFORMING THE MEASUREMENT.

CAUTION

IF A SINGLE TUBE GAS SAMPLING PROBE IS USED FOR PRESSURE/DRAFT MEASUREMENTS, BE SURE THAT IT IS CLEAN AND DRIED

BEFORE CONNECTING TO THE PRESSURE INPUT.

CAUTION

A +300HPA (OR –300HPA) OVER-PRESSURE CAN PERMANENTLY DAMAGE THE PRESSURE SENSOR.

3.2.3 Smoke Index Measurement (optional)

This method consists of taking a gas sample from the center of the gas pipe behind the heat exchanger and crossing it
through a special filter paper.
The color of the spot on the filter is compared with a graduated (from 0 to 9) reference scale and it is called “smoke
index”.
You can type in the instrument up to 3 smoke index values; the analyzer calculates the average value and print these
values on the report.
Normative and laws about the air pollution, describes the procedure: DIN51402, 2116, 2117 and 2297 VDI directives,
ASTM D 2156-63 T, etc.

3.2.3.1 Measuring Instruments (optional)

1. Smoke pump: it should suck 1.63 litres ±0.07 l (normalized to 0°C, 760mmHg) through a 1 cm2 filter.

2. Smoke index reference table: it is a grey scale sheet with 10 different areas numbered from 0 to 9. The number 0
corresponds to a 85% ±2.5% reflection. Every area reflects 10% less than the previous one. The scale is used to
compare the scale with the paper filter and to calculate the smoke index.

3. Paper filter: When it is clean it has a reflection corresponding to the 0 scale index. It also has 3 litres per cm

a

minute (normalized to 0°C, 760mmHg) with a 200/800 mmwc resistance to the air flux.

3.2.4 Other Measurements

The analyzer has an auxiliary input for special probes connections. Available probes are: ambient CO monitoring and
natural gas monitoring probes.
An optional operative mode is the leakage pipe test to check gas network tightness using pressure decay method at
programmable interval time.

4 RECOMMENDATIONS

 The analyzer should be used in environments where the temperature is between -5°C and +45°C.
 When the analysis is complete, before turning the instrument off, remove the probe from the gas pathway and wait

about 30 seconds, cleaning the pneumatic circuit from gas.

 Do not use the analyzer with clogged filters or filled with humidity.
 Before placing the probe in the case, be sure that the probe, the water trap and the hose are clean and cold.
 If you have ordered a double hose sampling probe, insert both connectors to the instrument during the gas analysis

(pay attention to color correspondecy).

 To empty the water trap from the condensate water, remove the draining plug. DO NOT OPEN the water trap. DO

NOT leave the water trap without the draining rubber plug (cat. EE650081).

 For the best efficiency and accuracy, we suggest to calibrate the instrument every year.

WARNING

IF THE INSTRUMENT IS STORED AT TEMPERATURE EXCEEDING THE OPERATIVE LIMITS, THE ANALYZER WILL A FEW NEEDS SOME
