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, cremators and furnaces. It provides fast, accurate readings taken in the harshest of conditions. It has a range of probes from 400mm to 900mm in length with multiple material options from stainless steel to Hastelloy for corrosive environments to ceramic or silicon carbide for temperatures up to 1,400 °C. There is no chance of thermal shock or moisture condensing in the sensor as the analyzer uses a close coupled extractive sample method with the sensor in an oven maintained at 700°C. When utilising the Pitot effect, the sample is vented back inside the flue and no instrument air is required for sampling. Blowback and air ejector options are available if the application is more demanding, such as coal fired furnaces.
