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. Coming with user selectable 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.
- User selectable ranges 0-100, 0-150 and 0-200 ppm (Factory calibration 0-200 ppm)
- 4-20 mA o/p (For Voltage Output see the GDA 2625)
- 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
