Manufactured by SST, the Screwfit zirconium dioxide oxygen sensor is specifically designed for demanding combustion industry applications.
Its threaded probe design ensures straightforward installation and is well-suited for use in industrial coal, oil, gas, or biomass boilers, as well as in continuous emissions monitoring and controlled atmosphere systems.
The sensor operates using SST’s proprietary closed-loop measurement system, which provides continuous oxygen level monitoring along with a built-in heartbeat signal that alerts users to any operational issues in real time.
Thanks to its non-depleting sensor cell technology, the unit delivers long-term performance without needing a reference gas. Calibration is quick and simple with any known gas—including ambient air.
Capable of withstanding extreme temperatures from -100°C to +250°C, the sensor delivers rapid response in under four seconds. It provides a linear output signal across the full 0.1 to 100% oxygen range and offers a service life of up to 10 years, depending on the application environment.
