Michell Instruments XZR400 oxygen analyser

The Michell Instruments XZR400 oxygen analyser is designed to measure trace levels of oxygen in pure, inert gases such as nitrogen, argon, helium and carbon dioxide.

Capable of detecting oxygen down to 0.01 ppm, the analyser is used to ensure the purity of gas produced by cryogenic air separation.

The product uses a MSRS zirconium oxide oxygen sensor, which contains a metallic sealed reference and ensures long-term repeatability of measurements. The MSRS means that no reference air is required. The technology is non-depleting, which gives the sensors a long life span of over seven years. Calibration is required every three to six months and can be carried out with just one calibration gas, saving time and money.

The range features four configurations: rack, wall, bench mount and transportable. All models include an intuitive touch-screen interface for quick and easy operation, barometric pressure and digital flow meters. One or two 4–20 mA outputs are available and other options include digital outputs such as Modbus RTU over RS485 protocol, RS232, internal or external sample pumps and process pressure correction.
