Oxygen Analyzers in Safe or Hazardous Areas Michell XTP601

Oxygen Analyzers in Safe or Hazardous Areas:

A range of trace oxygen analyzers utilizing Michell’s Metallic Sealed Reference Sensor (MSRS) technology. Designed to measure O2 as an impurity in pure inert gases such as N2, CO2, He, Ar and Kr. The XZR400 can also be used for cylinder fi lling and other applications where a precise measurement of oxygen is required. There are 4 different chassis to choose from and various internal options including pumps, fl ow alarms and digital communications to match customer needs.

Michell XTP601:

The analyzer provides a local HMI for the user to access all the functions of the analyzer through the glass via capacitive buttons. As well as displaying the target gas concentration, there is a status bar showing messages. The user can scroll through the front screens to see a graph of the latest period (user defined), min and max values, reading from an external sensor and alarm history.
