JS Probe

SIRO2 C700 JS Probe

The JS probe is a heated probe that incorporates a SIRO₂ C700 all ceramic oxygen sensor, shielded by a stainless-steel sheath enclosure for extended life in flues and boiler environments. It is used for measurement and control of oxygen sensitive combustion environments. The heated sensor operates in situ, and measures oxygen concentration real time, without the need for expensive gas sampling, or gas extraction equipment. The probe comes with a K-type thermocouple.
