Instruction Manual MM850481 ed.01
2.8 Smoke measurement
Smoke index measurement is done by using a hand pump (supplied as an accessory), the results cam be memory
stored and printed in the report.
2.9 Remote temperature probe
A remote Pt100 probe is available for combustion air temperature measurement from –10°C to 100°C. This probe is
strongly recommended mainly in forced air boiler to obtain an accurate calculation of the efficiency.
2.10 T+RH% probe
Optional probe for simultaneous measurement of ambient temperature and relative humidity (%RH) for comfort index
computation.
2.11 Ambient CO probe
Optional probe to monitor CO concentration and therefore safety condition in the boiler room. The instrument gives
acoustic and visual alarm if the set limit (according to the OSHA recommendation) are exceeded.
2.12 Natural gas probe
Optional probe to monitor CH
4
and natural gas concentration and detect and locate the position of a gas leak into the
domestic pipe network.
2.13 Leakage checking mode
To check gas network tightness using a pressure decay method at programmable interval time. It uses the internal
pressure sensor and a Eclipse leakage procedure.
2.14 Burner pressure probe
A 1 meter 8x4mm silicon hose is used to check the pressure inside the burner when you are installing the heating
system.
2.15 Pitot tube
The EGA4 analyzer can be connected to a Pitot tube for gas speed measurements.
2.16 Calibration certificate
Each EGA4 portable gas analyzer, is factory calibrated and certified against Eclipse Standards, that are periodically
certified by an International recognized Laboratory, and shipped with a Report of Calibration stating the nominal and
actual values and the deviation errors.
