ST Carbon Probe

SIRO2 ST Carbon Probe

The ST carbon probe incorporates a SIRO₂ all ceramic oxygen sensor, shielded by an Inconel 600 sheath for use in carburising furnaces. The probe design is specifically intended for small apertures into furnaces. It is used for measurement and control of oxygen sensitive environments at high temperatures. The sensor operates in situ, and measures oxygen concentration in real time, without the need for expensive gas sampling, or gas extraction equipment. The probe comes complete with a K-type thermocouple.
