The XZR400 Michell oxygen analyser is designed to measure oxygen as an impurity gas in inert gases such as nitrogen, carbon dioxide helium, argon, even chromium. The XZR 4000 belongs to the category of oxygen analysers using Michell’s Metal Sealed Reference Sensor (MSRS) technology.

It is used for cylinder filling and other applications where accurate oxygen measurement is required. Choose from three different housings and configurations, including pumps, flow alarms and digital communication, for a complete customisation (more in the accompanying documentation).

The rack-mount unit can be supplied with an EA Easidew compressed air dew point transducer or SF82 compressed air dew point transducer mounted inside the housing.
