The GDA 2530 Sulphur Dioxide gas sensor is a 2 wire 4-20 mA Loop Powered device with a range of 0-20 ppm Sulphur Dioxide. It has an electrochemical sensing unit which is temperature compensated and easily replaceable.
Designed, manufactured and supported locally in Australia.
The sulphur dioxide gas sensor electronics are housed in a robust ABS sun tolerant plastic enclosure. The sensor element is on a pluggable lead allow ease of replacement.
Poisoning: GDA sensors are designed to operate in a wide range of harsh environments and conditions. However, it is important that exposure to high concentrations of solvent vapours is avoided, both during storage and operation.
