2.1
Keypad & Display
The easy to use 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
The
3000-4000 series
can be equipped with a built-in, rugged, impact type printer. It uses a low cost common roll non-
thermal of paper (58 mm large, 18 meters long) , more readable, long life 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 lengths, shapes 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
Sensors
The
3000-4000 series
use long life sensors for O
2
, CO (H
2
compensated), NO, NO
2
and SO
2
.
An automatic internal device diluted the CO concentration when a high level of CO is identified by the instrument. Dilution
system allows to extend the measuring range of the CO sensor up to 10%.
The optional Autozero valve for quick start-up allows the operator to switch the instrument with the gas probe in the
stack.
Four acoustic and visual alarms can be set on four programmable parameters.
2.5 Temperature
probes
A thermocouple type K is incorporated in 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 Draft. Easy to change to and from pressure
analysis and stack Draft. Easy to change to and from pressure analysis with a single-key operation.
As an additional standard feature , the instrument is equipped with 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.
