The XZR500 oxygen analyzer from Michell Instruments is designed to determine the excess 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. It provides fast, accurate readings taken in the harshest of conditions.
