Apera Instruments AI5527 Value Series Portable pH Meter Kit for Strong Alkali and High Salinity Solutions

Features:

• Equipped with Swiss LabSen® 843 Refillable pH/temp. Electrode, designed for measuring strong alkaline and/or high salinity solutions.
• Intelligent Functions: Self-Diagnosis of out-of-range value and electrode invalidation, 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-SA Portable pH Meter Kit: Designed for professional pH measurement of strong alkaline and/or high salinity solutions with the help of the LabSen 843 pH/temp. Electrode. Also good for general water solutions. 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 843 pH/temp. Electrode: Built with proprietary sensor technology and premium materials from Switzerland, LabSen 843 pH/temp. Electrode is designed for measuring strong alkaline and/or high salinity solutions, minimizing alkali measurement error.
• 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.
• Swiss HA glass membrane: LabSen HA membrane is made for strong alkaline solutions (10-14 pH) and high salinity solutions, effectively minimizing alkaline errors caused by sodium ions. Compared with conventional electrodes, its service life testing these samples is 5 times longer.
• 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 843 ATC pH Electrode Electrode
• Feature: HA Glass Membrane
