Zirconia Oxygen Analyzer System
Zirconia (ZrO2) oxygen measurement system: 0.1–25% or 0.1–100% O2, 0.5% O2 accuracy after calibration.

In-situ zirconia probe for combustion efficiency and O2/COe.
The ZTR-4 is an in-situ combustion analyzer measuring residual O2 and combustibles (COe) directly in the flue at temperatures up to 700 °C. Boiler combustion trim reduces fuel consumption and NOx emissions.
A directly-inserted heated zirconia cell measures flue O2 at process temperature. An optional COe detector measures unburnt combustibles, allowing closed-loop combustion trim for maximum efficiency.
