GDA 2525 : Carbon Monoxide Gas Sensor
The GDA 2525 Carbon Monoxide (CO) gas sensor is a 2 wire 4-20 mA Loop Powered device. It has an electrochemical carbon monoxide sensor unit which is temperature compensated and easily replaceable.
Designed, manufactured and supported locally in Australia.
The Carbon Monoxide gas sensor electronics are housed in a robust IP56 ABS sun tolerant plastic enclosure. Factory calibrated optional ranges of 0-100, 0-150 and 0-200 ppm . The Carbon Monoxide sensor element is on a pluggable lead to allow ease of replacement. The sensor head and its electronics are housed in a metal enclosure giving it excellent RFI and EMC compatibility with a splash proof cover giving an IP53 rating.
- 4-20 mA o/p
- Low cost replaceable gas sensor element
- Easy to install
- Easy to calibrate (only gas and multimeter required)
- ABS sun tolerant IP56 housing with sensor element IP53
- Australian Factory Certificate of Calibration
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.
