ZIRCONIA BASED OXYGEN ANALYZER FOR
LOW TEMPERATURE (room – 600°C)
MOD. BT 300

In situ mounting

No calibration

Good stability

Suitable for dusty process

Suitable for hostile process
This analyser is based on an Yttria fully stabilized zirconia element. It represents an excellent solution for oxygen measuring
after combustion directly in the stack avoiding all expensive and complicated flue gas sampling and conditioning system.
The analyzer, whose probe is equipped with an armoured electric heater, can be used in processes with temperature within
room temperature and 600°C. The K type thermocouple built inside the probe is used for regulating the temperature of the
cell and for compensating the output of the cell at the actual temperature of the platinum electrodes. The calibration is no
longer necessary.
The attractive price is compatible with the high performance of this model thanks to its simple construction.
The analyzer consists of the probe (several lengths available), the electronic transmitter and the flowmeter box.
All parts of the analyser have been designed, produced and tested by our staff.

The compact and resistant probe model 5175, is fully produced in stainless steel. The flue gas gets in contact with the
cell without any circulation inside the probe itself.
The probe is mounted directly into the process using its four holes flange. The probe is produced in three different
standard lengths: mm. 350, 500, 1000 under flange.
Outside the head two compression fittings for mm 6x4 tubing for driving reference air and air or gas from a cylinder to
the cell to control the accurate Oxygen measuring are present. The probe can be mounted in any position. If possible,
we suggest the mounting in vertical position.
The converter model B705. It is a field transmitter that can convert the signals from the zirconia cell and the
regulation and compensation thermocouple of the Fer oxygen probe mod. 5175 Microprocessor based, connected to an
