Microx Online Analyser

The Microx Online is a wall or surface mounting instrument is for the
measurement of % Oxygen volume levels taken from a process line.
Typically the sample source would indicate the Oxygen level in the related
process and the Microx Online would be configured to initiate an Alarm
condition if the Oxygen content measured is too high.
This can be typically be for process purity reasons such as in Nitrogen
generation processes. Thus the inverse of the Oxygen measurement can also
indicate the level of Nitrogen in the process being measured.
