2.1
Keypad & Display
The tactile keyboard allows the operator to enter the main operative mode and all other complementary or auxiliary
modes following the menu driven instructions.
The high contrast graphic LCD (40x56 mm), equipped with an automatic back-light device, displays the measured and/or
calculated parameters in the preferred format (Zoom function). The above parameters can be also displayed in a graphic
mode.

2.2 Built-in
printer
EGA4 can be equipped with a built-in, rugged, impact type printer. It uses a low cost common roll of paper (58 mm large,
18 meters long) , more readable, long time and heat resistant better than the thermal printout on chemical paper. One
key instruction is enough to obtain one, two or more copies of the analysis report with header and company reference
data.

2.3
Gas sampling probe
Flue gas sampling probes with different length, shape and max. operating are available to match the requirement of
different applications. The sampling probe is connected to the instrument with a rubber hose through a combined module
of water trap and suspended particle filter.

2.4 Measuring
cells
EGA4 uses long life sensors for O
2
, CO (H
2
compensated), NO, NO
2
and SO
2
. An automatic device exclude
automatically the CO sensor when CO high concentration level is identified.
Four acoustic and visual alarms can be set on four programmable parameters.

2.5 Temperature
probes
A thermocouple type K is incorporated on the tip of the gas sampling probe to measure the flue gas temperature. This
thermocouple is suitable for measurements up to 800°C (max 1000°C for few seconds). Temperature measurement and
gas sampling from the flue gas pipe are thus always performed in the same site.
The probe is connected to the instrument with the appropriate compensated cable and connector. A Pt100 resistance
thermometer (local jig or remote sensor) is used for the air temperature measurement and best efficiency calculation.

2.6 Pressure
sensor
The instrument is equipped with an internal sensor for pressure and stack draught. One key instruction move the
operative mode to and from this function to gas analysis and viceversa. The instrument has, as standard feature, a
differential pressure sensor.

2.7
Fuel technical data
The instrument includes as standard the technical data for 4 of the most common fuels.
Using the optional GasConfig software, it is possible to modify or add data of up to 10 different fuels.
