LabSen 373 Flat pH/Temp. Electrode for Surface Test

• Proprietary pH sensor technology and premium materials from Switzerland
• Special LabSen flat glass membrane, suitable for flat surface pH measurement such as skin, textiles, paper, and small-volume samples etc.
• Long-Life Reference System, improving the stability of reference electrode and prolonging the service life of the electrode
• Anti-clogging PTFE ring junction
• Built-in temperature sensor for automatic temperature compensation
• No more air bubbles inside the glass membrane thanks to the Swiss blue gel electrolyte.

Built with proprietary sensor technology and premium materials, Apera LabSen 371 POM-body pH Electrode is designed for flat surface pH measurement such as skin, paper, textiles, etc.

Special Flat Glass Membrane -  LabSen 371 pH electrode adopts a flat glass membrane with PTFE ring junction, making reliable surface pH test easier than ever.

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.

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.
