The AII GPR-1200 oxygen analyzer is designed for applications where trace oxygen or gas purity must be controlled at defined measurement points using advanced high accuracy instruments. The GPR-1200 compact portable oxygen analyzer features a 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 GPR-1200 ATEX is a standard low ppm portable oxygen analyzer offers a range of 0-10 ppm and an LDL of 50 ppb O₂, with the option of the XLT sensor for measuring in CO₂ backgrounds, and an internal sample pump. ATEX approved version available.

Applications: Servicing oxygen and nitrogen generators, spot checks of oxygen in tankers during delivery, semi-conductor pipeline validation, headspace checks in fermenters and brew tanks, leak checking processes.
