The Microx is a compact oxygen analyzer that has a remote sensor and three display module mounting options. It utilizes 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 100ppm is ideal for nitrogen generation or glove box monitoring. The Microx analyzer can also be supplied with measuring ranges up to 0 to 96% O2 for oxygen concentrators. The flexibility is further enhanced by different mounting options and multiple sensor types
