Oxygen probe

Oxygen probes are one of the most important sensors in the heat treatment industry. Only by determining the exact oxygen content in the atmosphere can the correct conclusions be drawn for the gas mixing ratio in order to enable an optimal process. Therefore, the oxygen probes should work reliably and accurately, but also have a long service life, be easy to clean and easy to repair and calibrate.

For this reason, Avion Europa offers 2 oxygen probes that meet your requirements.

Gold probe – oxygen probe

Bazooka oxygen probe

Gold probe – oxygen probe

Reliable and economical

The heart of the GOLD PROBE is an Zirconium Oxyde sensor which we stabilzed with Ytrium.
This guarantees a long lasting accuracy.

Bazooka oxygen probe

Designed for endogas generators and constructed for high temperature and high carbon applications.

With the Bazooka oxygen probe, Avion Europa offers an innovation for measuring and controlling the gas composition in endogas generators. This oxygen probe is inserted through a 1 1/4 “opening on the side of the generator and takes samples independently.

Since the life of a lambda probe is very limited and the results fluctuate a lot, the Bazooka should be your next oxygen probe.

It was specially designed for endogas generators, but can also be installed in rotary kilns, muffle furnaces and chamber furnaces.

The ideal temperature for the longest possible service life of the Bazooka oxygen probe is between 810 ° C and 870 ° C.

After the endogas has cooled down, the bazooka takes a sample for measurement. The probe then transmits the results to the connected control unit. The probe is installed on the side wall in front of the mixing pump; therefore, easy installation and maintenance during operation is guaranteed.


The advantages of a Bazooka oxygen probe

  • Easy cleaning, repair and calibration
  • Reliable and long service life
  • Simple and immediate replacement of the lambda probe
  • Stable measurement and quick response
  • Control via dew point, O2, mV or “% C”
  • Operation via generator – no separate power supply
