Wall-Mounted Oxygen Analyzer for Industrial Gas Use
The GPR-2500 is a wall-mounted 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 pipework and easy to access maintenance free electrochemical oxygen sensors for user-friendly and cost-effective maintenance.
The sensors from AII have been designed to avoid potential weaknesses common in typical galvanic cell design. Our materials, construction and assembly methods have been continuously refined over decades. Each sensor type has been specifically engineered to provide the optimum balance between performance and longevity for individual applications. The result is confidence in the measurement and low maintenance. In the absence of oxygen, the sensor will produce zero output and the sensor is linear up to 100%, therefore only a span calibration is required in most cases.
For applications with a background gas containing more than 0.5% CO2 , the specially designed XLT sensor should be selected. With most standard electrochemical sensors an alkaline electrolyte is used and this is neutralised over time when exposed to acidic gases, such as CO2 . To combat this, AII developed the XLT sensor with a special electrolyte formula which has the added benefit of being able to operate in temperatures as low as -10°C.
