The GDA 3300 Sulphur Hexafluoride (SF₆) detector provides reliable long term detection of SF₆ gas at low levels. It has a configurable analog output of 4-20 mA; 0-20 mA; 0-5 V; 0-10 V. There is also a volt free relay which can be user programmed to operate anywhere within the sensor range. The unit is powered from 24 VDC.

Designed and manufactured locally in Australia.
