Monitors Oxygen in General Purpose and Hazardous Areas
Features
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
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 electrochemical oxygen sensors for user-friendly maintenance.
