Industrial Oxygen Analyzers (GPR-x600 & GPR-3100)
High-accuracy oxygen analyzers for industrial gases, from low-ppm trace O2 (GPR-1600) through percent (GPR-2600) to purity (GPR-3100).
Key Features
- High accuracy (±0.02 ppm in lowest range)
- Four measurement ranges with manual or auto-ranging
- GPR-1600: 0–10 ppm up to 0–1 % O2; GPR-2600: 0–1 % up to 0–25 %; GPR-3100: 0–100 % up to 90–100 %
- XLT sensor option for backgrounds with > 0.5 % CO2
- Integrated bypass valve (GPR-1600)
- 4–20 mA isolated, 0–1 V and 0–5 V outputs; range ID output
- Two user-adjustable alarm relays
- RS485, RS232 or USB communications
- Stainless steel wetted parts
- Bench, 19" rack, panel or wall mounting
Overview
High-accuracy oxygen analyzers for industrial process gases from low-ppm trace O2 (GPR-1600) through percent (GPR-2600) to oxygen purity (GPR-3100). Common HMI across the range; bench, rack, panel or wall mount.
Working Principle
All three analyzers use AII galvanic oxygen sensors, which produce zero output in the absence of oxygen and are linear up to 100 %, so only a span calibration is normally required. The GPR-1600 has an integral bypass valve to protect the trace sensor; the GPR-3100 adds a temperature-controlled sample system for an isothermal sample. Barometric pressure and temperature compensation are standard.
Applications
Benefits
- One common chassis, HMI and menu structure across the range
- Span-only calibration in most cases thanks to linear sensors
- 24-month sensor life with normal usage
