ATEX Certified Oxygen Analyser for PPB, PPM, Trace and Percent Level O2 Measurements

Jan 16 2008

Advanced Instruments (USA) GPR-18MS/18/28 series Online Oxygen Analyser combines their proven advanced galvanic electrochemical oxygen sensor with its fast response and long life design with a newly acquired ATEX Certification (Ex d IIB+H2 T6, CE) for hazardous area classification Class 1, Division 1, Groups B, C, D service and is NEMA 3/4/7/9 rated.
The GPR-18MS/18/28 is linear over all full scale (F.S.) ranges of analysis: 0 – 1 parts-per-million (ppm), 0 – 10, 0-100, 0-1000, 0-1%, 0 – 5%, 0 – 10%, 0-25%. The O2 analyser comes with a 5ppb sensitivity and 1ppb resolution from the LED display. 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 and 0-1VDC is provided. The compact, disposable oxygen sensor design requires no
maintenance and features < 0.5% accuracy under constant conditions along with a fast 7 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.
