Apera Instruments AI5541 Value Series Portable pH Meter Kit for Purified Water

Features:

• Equipped with Swiss LabSen® 803 Glass 3-in-1 pH/Temperature Electrode designed for quick and stable pH measurement of pure water (RO/Drinking/distilled/deionized water) and low ion concentration solutions.
• 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-PW Portable pH Meter Kit: Designed for professional pH measurement of pure water such as surface/storm/drinking/RO/distilled water and other low ion-concentration solutions with the help of the LabSen 803 pH/Temperature Electrode. Also suitable 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 803 Glass 3-in-1 pH/Temp. Electrode: Built with proprietary sensor technology and premium materials from Switzerland, LabSen 803 pH/Temperature Electrode is designed for quick and stable pH measurement of pure water (storm/surface/RO/drinking/distilled/deionized water) and low ion concentration solutions.
• Specialized Junction and Electrolyte: The moveable sleeve junction allows free flow of the reference electrolyte, quickly generating stable readings in low ion concentration solutions. Apera's proprietary blue gel inner solution does not flow at all, which means it will never generate air bubbles. It is not only more convenient to use, but also improves the measurement accuracy by eliminating heat convection in the inner glass membrane.
• Swiss patented pH/temperature combination structure: Increases the temperature response time by 40% compared to a conventional isolated built-in thermistor, accelerating ATC and the stabilization process.
• 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 803 ATC pH electrode Electrode
• Feature: movable sleeve junction, and L-type membrane designed for pure water and low ion concentration water solutions.
• Application: drinking/distilled/RO/deionized/boiler/storm/surface water
