Oxygen Transmitter


The SenzTx is a compact and robust O2 transmitter 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 SenzTx transmitter can also be supplied with measuring ranges up to 0 to 100% O2 for oxygen concentrators.
The flexibility is further enhanced by process connection multiple output options.
