The CarboProbe CP is a very simple, low cost oxygen probe with an easy-to-read digital meter displaying oxidation/reduction.

It is especially designed for potters.


The CarboProbe CP is supplied without a thermocouple.

The advantages of measurement of oxidation/reduction include:

  • Fuel savings – An economical firing depends on supplying enough oxygen, without waste of energy from heating excess air.
  • Reliable glaze colours – Knowing the right level of reduction every firing gives you the colors you want, firing after firing.
  • Reduced air pollution – Use the CP Probe as a guide for stoking wood-fired kilns to reduce wood consumption and unnecessary ash and smoke.

This probe is based on the ZRO2 zirconia oxygen sensor.
