HT Probe

SIRO2 C700 HT Probe

The HT probe incorporates a SIRO₂ C700 all ceramic oxygen sensor. The CP probe comes with an optional ceramic sheath for extended life and additional protection. 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 standard with an R-type thermocouple.
