• GLP standard data management, 500 data sets of storage, manual/auto storage, USB data output
• Rugged Structure Design: IP57 waterproof rating; Large white backlit LCD; Soft silicon case gives you a firm and comfortable grip
• Powered by AA batteries; the foldable stand also allows use as a benchtop meter
• Apera PH8500-HF Portable pH Meter Kit
• Apera Instruments PH850-HF Portable pH Meter is designed for measuring solutions containing strong acid, solutions containing hydrofluoric acid, and storage battery solutions. 
• GLP Data Logging and Data Management: Auto. or manual data logging with GLP data management (500 sets of data storage) and USB data output for further analysis and report.
• Easy Calibration: Quick and easy 1 to 3 points of auto. pH calibration, recognizing pH standards of 1.68, 4. 00, 7.00, 10.01, 12.45. The self-diagnosis function ensures pH calibration will be correctly performed.
• Data logger with USB Output: Auto. or manual data logging with GLP data management (500 sets of data storage) and USB data output for further analysis and report.
• Built Tough: The IP57 water-resistant structure makes the meter ideal for use in harsh environment. The rubber sleeve protects the instrument from general impact and gives you a firm grip.
• Large backlit LCD Display
  • Stability icon. Take the reading when the smiley face stays on screen.
  • Icons for finished calibrations
  • Simultaneous temperature display
  • Time
  • Manual storage icon and number
• LabSen 833: LabSen 833 glass-body refillable pH/temp. Electrode is designed for measuring solutions containing strong acid or hydrofluoric acid.
• Specialized Electrolyte: Apera's proprietary blue gel inner solution does not flow at all, which means it will never generate air bubbles. The electrode can work well even when being held upside-down. It is not only more convenient to use, but also improves the measurement accuracy by eliminating heat convection in the inner glass membrane.
• HF glass membrane: The equipped Swiss LabSen 831 Glass pH Electrode adopts a special HF glass membrane, which is resistant to HF corrosion and is capable of measuring solution containing HF acid for up to 1000 times. (measurement time<1 minute, and HF concentration should be less than 0.1mol/L or 0.2% wt%)
• Silver-ion-trap reference system: The combination of a Long-life reference system and a silver ion trap. The silver ion trap will absorb all the exuded Ag+, ensuring that there's no Ag+ in the reference electrolyte, and avoiding junction clogs caused by samples containing sulfides, proteins or TRIS buffer solutions.
