Products > Microx Oxygen Analyzer

Overview

The Microx is a compact and robust oxygen analyser that utilises zirconia or electrochemical technology to give a reliable measurement of oxygen concentration. The zirconia sensor offers fast response time and a long service life with virtually no drift, whilst the electrochemical sensor allows measurement in background gases containing hydrocarbons.

The minimum output range of 0 to 10ppm is ideal for nitrogen generation or glove box monitoring. The Microx analyser can also be supplied with measuring ranges up to 0 to 96% O2 for oxygen concentrators. The flexibiliy is further enhanced by different mounting options and multiple sensor types.
