Labideal GPR-1600 UHP B PPB Oxygen Analyzer Base Model

This oxygen analyzer utilizes a UHP (ultra high purity) Pico-Ion oxygen sensor capable of precisely measuring oxygen concentrations ranging from less than 1 PPB to 100 PPM over a 12 month service life with no periodic maintenance required, integral temperature control enhances stability, menu driven controls and a fully automated (auto-zero, auto-cal, remote access) ultra-clean leak free 316L stainless steel sample system.

• Calibration – certified gas of O2 balance N2 approximating 80% of range above analysis range recommended for optimum results
• Flow sensitivity – none, between 1 – 3 scfh, 2 scfh recommended
• Barometric pressure and temperature, heated sample system and sensor housing compensation
• Controls – water resistant keypad, menu driven range selection, calibration, alarm and system functions
• >0.995% over all ranges linearity
• Response time – 90% of final reading in less than 60 sec
• Less than 0.5% full scale sensitivity
• 316L stainless steel wetted parts
• Pressure regulate to 20 – 50 psig inlet and atmospheric vent not to exceed 5 Inch water column
• Sensor – model GPR-13-2000UHP, 18 months expected life at 25 deg C, 1 atmosphere, average O2 less than 100 PPM and 12 months warranty time
• Alarm type – two adjustable form C non-latching relay contacts, weak sensor indicator, power and system failure
• Auto-ranging or manually lock on single range
• Data acquisition – selectable data point intervals
• Recovery time – 9 PPM oxygen level, 1 min duration, 10 PPB oxygen target, 15 min recovery on N2
• Sample system – manual pressure regulation, flow control and indicator pneumatic (minimum 80 psig air supply) sample and span inlet valves, bypass and isolation valves, integral oxygen scrubber (for consistent zero gas) and valves, electro polished tubing, orbitally welded or VCR connections
• Auto-zero, span calibration
• 12 months warranty
