Analytical Industries GPR-3500 Portable Purity Oxygen Analyser

The Analytical Industries GPR-3500 Portable Purity Oxygen Analyser is a battery-powered instrument designed for verifying enriched oxygen gas concentrations in field and plant environments.

The product supports oxygen measurement from 0 to 100%, with available ranges up to 90 to 100% oxygen for purity applications. Built for flexible use at multiple measurement points, the analyser combines an internal pressure regulator, flow control and a sample bypass valve to help operators achieve quick response when moving from point to point.

The portable analyser uses Analytical Industries’ electrochemical oxygen sensor technology, developed over decades and engineered for long service life. The sensor provides a five-year expected life, while temperature compensation supports improved measurement accuracy and stable operation.

With integrated measurement data-logging and battery-powered portability, the analyser gives technicians a practical tool for documenting oxygen purity checks without relying on fixed instrumentation. Its internal pressure regulator accepts sample inlet pressures up to 3600 psig, expanding its usefulness across demanding process and gas-generation applications.
