Premium Portable Oxygen Analyzer
Analytical Industries offer portable oxygen analyzers for applications where trace oxygen or gas purity must be controlled at defined measurement points using advanced high accuracy instruments. The Model GPR-3500, packaged in a compact yet rugged enclosure, with stainless steel wetted parts, integrated flow meters and needle valves, offers purity measurement for inert gases, carbon-dioxide and oxygen. Customers who use the GPR-1200 compact portable oxygen analyzer value the 4-way valve that allows a gas sample to be trapped in the sensor for faster oxygen measurement times when moving from point to point. This feature also effectively helps to protect trace oxygen sensors from premature depletion due to exposure to ambient oxygen levels. Longer sensor life-times allow very economical operation and low cost of ownership for this market leading portable oxygen analyzer range.
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.
