Gas Detectors and Industrial Measurement Instruments

GPR-2500, GPR-3100, GPR-3500 Fixed Type Oxygen Analysers (0-100%)

Product Specifications

GPR-2500
Suitable for both general purpose and hazardous area use, the GPR-2500 is wall-mounted and measures %VOL oxygen. It features a lightweight NEMA-rated external enclosure and all-stainless-steel wetted gas paths. It is easy to maintain and operate. All these features make the GPR-2500 a user-friendly, high-performance instrument.

GPR-3100
Thanks to Analytical Industries Inc.'s advanced sensor technology, this instrument series delivers high-accuracy measurements for industrial use. To enhance measurement accuracy, it provides an isothermal environment via a temperature-controlled sampling system. It features different chassis options that can be configured based on use. It is available for panel, wall-mount, and benchtop installations. It features 2-stage adjustable alarms. Operation, maintenance, and sensor replacement are exceptionally straightforward.

GPR-3500
A lightweight and portable oxygen purity analyser. It measures 0-100%vol. The internal system is constructed from stainless steel and compensates for atmospheric pressure and temperature variations to provide precise measurement. It accommodates flowmeter and valve configurations as well as an optional internal pump unit.

Measurement and Standards Approach

In process gas analysis, as much as the measuring range, sample gas pressure, flow rate, background gas, moisture/condensation risk, sensor material, and calibration gas are also critical selection parameters. In hazardous area applications, certifications such as ATEX/IECEx must be verified according to the model variant; analogue/digital output and alarm requirements for process control must be evaluated separately.
