IN-SITU Oxygen analyser ROC-3 

The In-Situ Oxygen analyses is used to measure oxygen in industrial furnaces and other incinerators at temperatures of up to 600°C (optional 1400°C).

The measurement is based on the low-maintenance and reliable technology of Zirkonium dioxide. ROC-3 is a compact and robust sensor with high measuring accuracy, very low drift of measuring signal and a long lifetime.
