GPR-1900 User’s Manual GPR-2900 User’s Manual Datasheet

Flexible, Easy Maintenance Oxygen Measurement

Features

Measurement ranges from 0-10ppm 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

A panel mounted oxygen analyser with a remote sensor allows flexibility of installation. The GPR-1900 gas analyzer is suitable for trace oxygen measurements as low as 0-10 ppm; the GPR-2900 measures O2?up to 100%. The remote sensor block allows a very easy oxygen sensor replacement for simple and fast maintenance and low cost of ownership. All versions can be locked manually to a single range or auto-range. The user is always aware of the oxygen measurement range used via the range ID output.
