Description

SST’s zirconia oxygen sensor probes are built for demanding environments, including polluted applications such as boiler exhausts. Available in three lengths, they’re ideal for installations requiring deeper probe insertion, such as insulated flue pipes.

Using a closed-loop measurement system, the sensors deliver continuous, accurate O₂ readings and feature a heartbeat signal for real-time status monitoring. Their non-depleting technology ensures a long service life with no reference gas required. Calibration is simple and can be done using any known gas, including fresh air.

With flexible probe and cable options, standard or fast response times, and a wide temperature range, these sensors offer reliable, linear performance from 0.1 to 100% oxygen.
