Products comparison for %C

We provide a wide range of oxygen probes (including low cost oxygen probes) for any heat treatment systems, for potters, ceramic industry, universities or laboratories. Most of our oxygen probes are based on the ZRO2 ceramic oxygen sensors (most commonly used oxygen sensor).
The ST E is 100% compatible with the Eurotherm/SE/Barber-Colman probe. It is an updated version, more robust and patented.
