XZR-500 Series

Stack Gas Analyzer
The XZR-500 oxygen sensor from Michell Instruments is designed to determine the excess of air required for optimum combustion.

It uses advanced Zirconium Oxide technology to measure levels of oxygen in harsh conditions such as boilers, incinerators and furnaces.

Together with the XCU-500 analyzer, it provides fast, accurate readings taken in the harshest conditions.
