The Ntron Senz-Tx oxygen sensor transmitter is a compact and robust O₂ transmitter that 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, while the electrochemical sensor allows measurement in background gases containing hydrocarbons.

The Ntron Senz-Tx oxygen sensor 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.
