ATEX Certified Oxygen Analyser
Aug 05 2009
Advanced Instruments’ (USA) GPR-1800AIS / GPR-2800AIS series Online Oxygen Analyser combines their proven advanced galvanic electrochemical oxygen sensor with its fast response and long life design with ATEX Certification (Ex d [ib] ib IIB T4, CE) for hazardous area classification.
The GPR-1800AIS / GPR-2800AIS is linear over all full scale (F.S.) ranges of analysis: 0 – 10 parts-per-million (ppm), 0-100, 0-1000, 0-1%, 0 – 5%, 0 – 10%, 0-25%. The precision stainless steel sensor housing, wetted parts and enhanced temperature compensation circuitry produce accuracy / repeatability of < 0.5% F.S. with an expected life of 24 – 60 months. A signal output of 4 – 20mA is provided.
The compact, disposable oxygen sensor design requires no maintenance and features < 0.5% accuracy under constant conditions along with a fast 10 second response time. The high current output also reduces the temperature dependence at low oxygen levels and produces a very stable signal output that lengthens calibration intervals. This allows the sensor to exhibit superior performance in inert gases, gaseous hydrocarbons, acid and mixed gases.
Not many on-line trace oxygen analysers provide as much performance for the price as the Advanced Instruments’ GPR-1800AIS / GPR-2800AIS series ATEX certified Oxygen Analysers.
