GPR-1100 & GPR-1200 Portable Trace Oxygen Analyzers
Compact portable analyzers for spot-checking trace ppm O2 contamination.
Key Features
- Four measurement ranges from 0-10 ppm to 0-10,000 ppm (1%) O2
- Sensor options for inert, hydrocarbon, mixed acidic, hydrogen or helium background gases
- General Purpose or Hazardous Area (ATEX, IECEx, cMETus, UKEx) configurations
- GPR-1200 adds sensor bypass valve, metering valve and flowmeter
- Integral measurement data logging
- LCD screen displaying O2 concentration
- Sensor life of up to 24 months
Overview
The GPR-1100 and GPR-1200 are portable trace oxygen analyzers designed for periodic verification of oxygen concentration in a gas stream. The compact GPR-1100 suits quick point-to-point spot checks, while the GPR-1200 adds a metering valve, flowmeter and sensor bypass valve for controlled sampling, faster location-to-location measurements, and extended sensor life.
Working Principle
An electrochemical sensor, selected to match the background gas (inert, hydrocarbon, mixed acidic gas, hydrogen or helium), measures trace oxygen concentration and displays the result on an LCD screen. The GPR-1200's bypass valve routes sample gas around the sensor between measurements, reducing sensor exposure and extending its service life.
Applications
Benefits
- Compact GPR-1100 ideal for quick spot-check verification
- GPR-1200's bypass valve speeds multi-location surveys and extends sensor life
- Hazardous-area certified variants available for use in classified areas
- Wide sensor selection covers difficult background gases without cross-interference
