Product description
BRIGON 500 NT measures CO
2
, CO, differential pressure as well as flue gas and ambient air
temperature. The instrument calculates O
2
, CO
undiluted
, lambda, stack loss q
A
and efficiency
(Eta).
The data are displayed in function oriented measuring windows or user selectable window in a
back-lighted display.
When storing a reading, as for example Oxygen concentration O
2
, the readings of flue gas
temperature and ambient air temperature as well as the calculated values q
A
, differential
temperature, Eta and CO
2
are stored and can be optionally printed.
Sensor calibration takes max. 90 seconds and is performed automatically after switching on
the analyser.
Flue gas analyser has an integral watertrap with particle filter. Damp from the flue gas is
condensed and collected in the watertrap. The filter prevents smut particles from getting into
the analyser.
Please, note that your flue gas analyser is a product designed, manufactured and sold solely
for the purpose of flue gas analysis of burners. So, please, use your analyser and its
accessories only for this purpose.
Should you require to use it for other purposes, please obtain our written permission to do so
first.
Keep these operating instructions in a safe place close to your analyser as quick
reference should the need arise.

Commissioning, handling, storage
Your BRIGON 500 NT is delivered with 4 mignon batteries. Even in switched off mode the
batteries supply the clock of the analyser so, that the batteries are discharging even if you do
not use your BRIGON 500 NT.
Therefore we recommend to remove the batteries from your analyser if you do not need it for a
few days.
To prevent an impairment of the electrochemical sensors, please avoid the use and storage of
your BRIGON 500 NT in the environment of perspirating substances, e.g. solvents. Do not use
these substances for cleaning your BRIGON 500 NT either.
Take care that no moisture or condensate gets into the analyser.
Always make sure the batteries resp. rechargeable batteries (option) are fully
charged, especially if the analyser has not been used for a long period of time.
Important Safety Instructions
Your BRIGON 500 NT has been developed and manufactured with the utmost care to ensure
safe and reliable operation over many years. As with all electronic appliances, you must be
aware of certain general precautions. These are intended for your safety and to protect the
analyser from damage.
Read these operating instructions carefully, and keep all documents in a safe place for future
reference.
Be sure that...
• you carry out only the routine maintenance according to the operating instructions.
Opening the case of the instrument can cause damage to vital parts. The warranty will
become void if repair/modifications are undertaken by unauthorised persons!
• after having changed parts of the BRIGON 500 NT which have an influence on the
accuracy of the measurement, the concerned measuring channel should be tested at the
authorised service point for the reason of quality management.
• Magnetic fields – emerging from the magnets of the soft case of the analyser – can set
off sparks, can have an influence on pacemakers, can disturb electronic and
electrotechnical components and can delete data memories.
Take care that...
• your power outlet data matches that of the charger. If in doubt, consult your dealer or
BRIGON MESSTECHNIK directly.
• Do not expose your BRIGON 500 NT to temperatures higher than 50°C (as they can for
example occur in a car being parked in the blazing sun). It could happen that the analyser
will get overheated and that especially the electrochemical sensors will be destroyed. Do
also avoid temperatures below -20°C.

• the charger is disconnected from the power outlet before cleaning the analyser. Use only
a damp cloth.
Do not use cleaning agents containing solvents!
