GPR-1000 Portable PPM Oxygen Analyzer

GPR-1000 Portable PPM Oxygen Analyzer

Accuracy: < 2% of FS range under constant conditions Analysis Ranges: 0-1000 PPM, 0-1%, 0-25% (CAL) FS Auto-ranging or manual lock on a single range Application: Oxygen analysis in inert, helium, hydrogen, mixed and acid (CO2) gas streams Approvals: Certified for use hazardous areas - see lower right Area Classification: Class I, Division 1, Groups C, D Calibration: Max interval—3 months. Use certified span gas with O2 content (balance N2) approximating 80% of full scale for fast 20-30 minute recovery to online use. Alternatively, air calibrate with clean source of compressed or ambient (20.9% O2) air on 0-25% range and allow 60 minutes on zero gas to recover to 10 ppm. For optimum accuracy, calibrate one range higher than the range of interest. Compensation: Temperature Connections: 1/8" quick disconnect Controls: Water resistant keypad; menu driven range selection, calibration and system functions Display: Graphical LCD 2.75 x 1.375”; resolution 1 PPM Enclosure: Painted aluminum NEMA 4X, 4 x 9 x 3", 8 lbs. Flow: Not flow sensitive; recommended flow rate 2 SCFH LED Indicators: LOW BATT (72 hr. warning); CHARGE mode Linearity: > .995 over all ranges Pressure: Inlet - regulate to 5-30 psig to deliver 2 SCFH flow; vent - atmospheric Power: Rechargeable battery, 60 day cycle, 8 hrs with pump Recovery Time: 60 sec in air to < 100 PPM in < 15 min on N2 purge Response Time: 90% of final FS reading in 10 seconds Sample System: None; Brass quick disconnect fittings Sensitivity: < 0.5% of FS range Sensor Model: GPR-12-100-M for non-acid (CO2) gas streams XLT-12-100-M for gas mixture with > 0.5% CO2 Sensor Life: 24 months in < 1000 PPM O2 at 25ºC and 1 atm Signal Output: 0-1V FS Temp.
