GPR-1200 is a 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.
