GPR-1000/1100/1200/2000/3500

 Portable Oxygen Analyzers for General Purpose and Hazardous Areas
The portable oxygen analyzer range from AII has several variants capable of measuring from parts per billion (ppb) to pure O2.

Featuring advanced galvanic trace sensors for parts per million (ppm) analysis with proven life times of up to 24 months in normal operation. Percent level analyzers have a life time of up to 32 months.

User-friendly Human Machine Interface (HMI) with a common menu structure throughout the range. Compact and robust enclosures designed to withstand the demands of industrial field use.

Integrated bypass on selected models that isolates the sensor when not sampling allowing trace levels of O2 to be measured quickly and vastly extends the life of the sensor. Optional sample system items include flowmeters, pumps, filters & scrubbers.
