Process Oxygen Analyzers for Hazardous Areas
GPR-2800 Series
The GPR-2800 series of process oxygen analyzers allows measurements of 0-1 up to 0-25% O2 in hazardous areas. Combined with our modular sample system, the gas analyzer will suit most installations for demanding oxygen analysis and will meet the needs of process customers around the world. Analytical Industries' proprietary long-life oxygen sensor technology allows a maintenance-free sensor operation of up to 32 months for low cost of ownership. The industry-proven and well recognised electrochemical gas sensor quality ensures the reliability of oxygen content measurements even at high carbon dioxide background.
