Compact Oxygen Transmitter | Ntron SenzTx

Compact Oxygen Transmitter – Overview

This compact and robust O2 transmitter 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. The electrochemical sensor allows measurement in background gases containing hydrocarbons. The minimum output range of 0 to 1000ppm is ideal for nitrogen generation or glove box monitoring. The SenzTx transmitter can also be supplied with measuring ranges up to 0 to 96% O2 for oxygen concentrators. The flexibility is further enhanced by process connection multiple output options. Applications include Nitrogen Generators, Oxygen Generators, and Glove Boxes.
