Apera Instruments AI5529 Value Series Portable pH Meter Kit for Strong Acid Solutions

Features:

• Equipped with Swiss LabSen® 833 pH/Temp. Electrode, designed for measuring solutions containing strong acid or hydrofluoric acid.
• Intelligent Functions: Self-Diagnosis of out-of-range value and electrode invalidation, auto. calibration, electrode slope display, Auto. power-off, easy parameter setting
• Rugged Structure Design: IP57 waterproof rating; 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 PH850-HF Portable pH Meter Kit: designed for measuring solutions containing strong acid, and/or hydrofluoric acid. Easy Calibration Easy 1-3 points of pH calibration, automatically recognizing pH standards of 1.68, 4.00, 7.00, 10.01, and 12.45.
• 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 LCD Display 
  • Stability icon. Take the reading when the smiley face stays on screen. 
  • Icons for finished calibrations  
  • Simultaneous temperature display
• LabSen 833: LabSen 833 pH/temp. Electrode is designed for measuring solutions containing strong acid and/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 833 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.
• Electrode: LabSen 833 ATC pH Electrode Electrode
• Feature: Special HF glass membrane
• Application: solutions containing Hydro fluo- ride acid or other strong acids.
