Michell Instruments XZR250 oxygen analyser

The Michell Instruments XZR250 oxygen analyser is designed for monitoring combustion control in industrial boilers. It was developed as a cost-effective, easy-to-operate instrument with a probe designed to cope with the high temperatures in the flue. Effective combustion control has growing importance for operators as it not only helps increase fuel efficiency but also ensures compliance with legislation on allowable emissions.

The XZR250 uses a zirconium-oxide sensor with a life span of up to seven years (depending on the fuel used) to keep maintenance to a minimum. A key benefit of the sensor is its fast response of less than 15 s to changes in oxygen concentrations of up to 90% of the range. It is also accurate to <0.25% O2, allowing optimum combustion control.

The XZR250 is requires no specialised tools for installation, is lightweight and has a fast start-up routine. The probe can be inserted directly into boilers up to 700°C and uses the Pitot effect to ensure the sample gas is sufficiently cooled to protect the sensor from damage without the need for complex sample conditioning. As with any process instrument, regular calibration is necessary to ensure the accuracy of the measurements. The XZR250 can use air as a calibration gas, making calibration cost effective and simple to perform.

When the sensor needs replacing, this can be done with minimal process downtime, using Michell’s sensor exchange program.
