Apera Instruments AI5539 Value Series Portable pH Meter Kit for Micro Samples

Features:

• Equipped with Swiss LabSen® 243-6 Glass pH/Temperature Electrode, designed for pH measurement of semi-micro samples (>0.2mL)
• Smallest test volume is 60µL with the use of the semi-micro container (included in the kit)
• 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-MS Portable pH Meter Kit: The meter is designed for lab-grade pH measurement in the field with a variety of intelligent functions in a rugged body, suitable for small-volume or test tube measurement with the help of the LabSen 243-6 pH/Temp. semi-micro electrode. 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 243-6 Semi-micro pH/Temp Electrode: Powered by sensor technologies and key materials from Switzerland, LabSen 243-6 Glass pH/Temperature Electrode (6mm in diameter), designed for pH measurement of semi-micro samples (>0.2mL).
• 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.
• LabSen S-type semi-micro glass membrane: 100mm in length and 6mm in diameter, low membrane resistance (<350MΩ), making reliable small-volume (>0.2mL) pH measurement easier than ever, and can be tested in high-temperature samples (up to 212°F).
• Long-Life Reference System: Composed of a glass tube, AgCl, and a reference silver wire. The top end of the slim glass tube is stuffed with cotton, which prevents the reaction between AgCl and electrolyte when the temperature changes. It improves the stability of reference system and extends the service life of the electrode.
• Electrode: LabSen 242-6 ATC pH electrode Electrode
• Feature: dimension of the sensor  is Φ6x100mm, fast-response S membrane
• Application: measurement for small volume samples (minimum volume: 60µL) and in test tubes.
