3 PHYSICAL DESCRIPTION
The EGA4 portable analyzer consists of a rugged and compact case, a mother board with all base function circuits, 2, 3
or 4 electrochemical cells, a gas pump, a keyboard, an LCD backlighted display, a Ni-MH rechargeable battery pack and,
optionally an impact printer.
The 2 pieces of the case are jointed by 8 screws. The batteries, the pneumatic circuit and the cells are positioned in the
rear of the analyzer and 2 screws locked the lid.
A pressure lid allows to remove the paper roll.

At the bottom of EGA4 you can see all sampling probe connectors: gas inlet, pressure and draught input, thermocouple
input for gas measurement and the 2
nd pressure inlet connector.
On the left side are the connectors for: line power charger, synchronous serial input connector for bar pen and keyboard,
the input for the auxiliary probes (T+RH%, leak checker, etc.) and the infrared LED for PC serial communication (an
optional IR/RS232 and software should be used to configuring and transfer the analysis data).
The operator interface is on the front of the instrument and it consists of: a high contrast LCD display and a 14 button
keypad. An automatic back-light device and a “zoom” function, make easier the data reading on the display. The most
used operation (analysis, draught, printing and smoke index) can be accessed by operator pressing a single key.
