The AII GPR-1100 Oxygen Analyzer is an industry standard portable analyzer for trace oxygen measurements down to 0.1 ppm. Supplied with stainless steel wetted materials, the instrument is also equipped with quick connect fittings to trap the sample in the analyzer and extend the oxygen sensor service life by avoiding air diffusing into the sensor.

Applications: Oxygen and nitrogen generators, storage holds on marine vessels post maintenance, oxygen in tankers during delivery, metal treatment processes, leak checking processes, double glazing manufacture, welding (under N₂ or Ar purge).
