• Apera PH8500-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.
• 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 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.
