Product Specification

O2S-FR-T2-18BM-C-RS485 Zirconia Oxygen Sensor System Description
The Zirconia Oxygen Sensor System offers a complete solution, removing the need for customers to develop their own electronics. Frequently used in combustion control systems, burning coal, oil, gas and biomass and in oxygen generation systems.

The Zirconia Oxygen Sensor System consists of SST’s fast response (<4s T90) zirconium dioxide (ZrO₂) screw fit sensor in conjunction with the OXY-LC oxygen sensor interface board.
