Portable Oxygen Purity Analyzer GPR-3500
Premium portable oxygen purity analyzer, 0–100 % O2, with stainless steel wetted parts.
Key Features
- Measurement range 0–100 % O2
- Accuracy < 2 % at constant conditions
- Response time T90 < 13 s
- Inlet pressure up to 248 barg (3600 psig) on GPR-3500 MOVR
- Stainless steel wetted parts
- Up to 30 days battery life
- 0–1 V output
- Barometric pressure and temperature compensation
Overview
The GPR-3500, packaged in a compact yet rugged enclosure with stainless steel wetted parts, integrated flow meter and needle valve, offers oxygen purity measurement for inert gases, carbon dioxide and oxygen. The GPR-3500 MOVR version accepts inlet pressures up to 248 barg (3600 psig).
Working Principle
A GPR-11-120-OP galvanic oxygen sensor, linear up to 100 % with zero output in the absence of oxygen, measures the sample with barometric pressure and temperature compensation. The battery-powered analyzer provides a 0–1 V output.
