Built with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 223 Glass Combination pH/temp. Electrode is designed for low ion concentration samples and titration as well as general water solutions. The electrode is compatible with TRIS buffer solutions.

LabSen S-type spear glass membrane - low resistance and high firmness, rendering fully stabilized readings in 15 to 30 seconds, and is yet 10 times stronger than traditional glass membranes, highly resistant to general impact, eliminating the chance of accidental breakage while inserting into food samples.

Movable Sleeve Junction - easy to clean, especially suitable for low ionic strength solutions, emulsions, and suspensions. The infiltration rate of the electrolyte can be adjusted by the tightness of the sleeve.

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.

Compatible with all Apera Instruments meters with BNC and RCA connectors such as PH910, PH9500, PH850, PC8500, and PH820. May NOT work with other brands' meters because the thermistor might be incompatible.
