Built with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 803 Glass-body pH/Temp. Electrode is made for pH measurements of pure water such as distilled and deionized water, and other low ionic strength solutions.

LabSen L-type glass membrane - fast response in low ionic strength solutions thanks to its ultra-low resistance formula (<50MΩ), providing fully stabilized readings in 30 to 60 seconds.

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.
