Analytical Industries Wall Mounted Percent Oxygen Analyzer

Description

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).
Ranges available: 0-1%, 0-5%, 0-10% & 0-25% O2

GPR-2500 A

The Analytical Industries GPR-2500 A model offers the temperature and an additional barometric pressure compensation as well as two user configurable alarm relays as standard. The instrument has the option of 12- 24 V DC or mains power. Available for general purpose areas.
Ranges available: 0-1%, 0-5%, 0-10% & 0-25% O2
