Tags: XZR400, Series, Oxygen, Analyzers, Michell, Instruments
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 filling 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, flow alarms and digital communications to match customer
needs.
See datasheet for the full specification of the XZR400 Series range.
