Description

Percent Oxygen Analyzer in NEMA Enclosure – AII GPR-2500

For General Purpose and Hazardous Areas

 

AII GPR-2500 Percent Oxygen Analyzer is 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. Simple to use, and providing best-in-class reliability in demanding industrial environments, our oxygen analyzers are available as fixed installation or as portable instruments for spot-checking processes.

 

Features:

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