It can also be used (when optionals are activated or external equipment is used) for a number of
measurement tasks, such as:
•
Flow velocity measurement of flue gas
•
Differential measurement of pressure and temperature
•
Combustibles detection with external HC sensor
You will find a list of all optionals for this analyzer on our web page or you can contact COSA or

2.3 Important general information (EN 50379) and VDI 4206
This analyzer is not designed to be used for continuous measurements.
Before using the analyzer verify the condition of the various parts of the analyzer, such as the
probe, the ambient air conditions, the condensate separator, star filter and the connectors for dam-
age and/or blockages.
When starting up the analyzer it will take between 1 – 3 minutes to set to zero depending on the
condition of the sensors and of ambient.
The minimum zeroing time of the analyzer to achieve correct measurement values can be ex-
pected by 1.5 minutes!
Caution: Exposure to acids; aggressive gases such as sulphur; vapours such as thinners, gaso-
line, alcohol and paint, etc. can damage, reduce the life of, or destroy the sensors.
The life of the sensors depends on how they are used, maintained and treated. Typical average life
expectations are: O
2
- 2 years; CO - 2 - 3 years; NO - 3 years, NO2 and SO2 approx. 2 – 3 years.
The use of the analyzer for regulatory purposes is subject to special regulations (for example a
periodical examination of the analyzer). Please obtain the appropriate regulations from your local
