- A panel mounted oxygen analyser with a remote sensor allows flexibility of installation. The GPR-1900 is suitable for trace oxygen measurements as low as 0-1 ppm; the GPR-2900 measures O2 up to 100%. All versions can be locked manually to a single range or auto-range. The user is always aware of the range used via the range ID output.
- Measurement ranges from 0-1ppm up to 0-100% O2
- Barometric pressure and temperature compensation
- Accuracy of better than 2% of range
- Two user configurable alarms
- Range ID output
- 12-28 V DC or mains powered options
- XLT sensor options for CO2 backgrounds
