Model GDA 2527 -Nitrogen Dioxide Gas Sensor

The nitrogen 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.

• 0-30 ppm Range (Other ranges on request)
• 4-20 mA o/p (For Voltage Output see the GDA 2627)
• Low cost replaceable gas sensor element
• Easy to install
• Easy to calibrate (only gas and multimeter required)
• ABS sun tolerant housing
• 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.
