Analytical Industries Wall Mounted Percent Oxygen Analyzer

The GPR-2500 is an industrial oxygen analyzer for percentage oxygen measurements in both general purpose or hazardous areas. Available in several variants, all of which are supplied in a lightweight NEMA enclosure with stainless steel wetted parts and easy to access maintenance-free electrochemical oxygen sensors for user-friendly and cost-effective maintenance.

Highlights

• Advanced galvanic electrochemical sensors
• Measuring oxygen in ranges: 0-1% up to 0-100% (model dependant)
• Accuracy of better than 2% of selected range
• Auto-ranging or fixed range (user selectable)
• Long lifespan of the GPR sensor of 32 months and more
• Simple to use HMI

GPR-2500 N (ATEX)

Base model percentage oxygen analyser with temperature compensation, loop powered (18-24V DC)
and with a 4-20mA output. Available for use in both general purpose and certified for use in hazardous areas (ATEX).
