Apera Instruments AI3107 PVC-Body Flat pH Electrode

Features:

• Proprietary pH sensor technology and premium materials from Switzerland
• Special LabSen flat glass membrane, suitable for flat surface pH measurement such as skin, textiles, leather, paper, culture medium etc.
• Long-Life Reference System, improving the stability of reference electrode and prolong the service life of the electrode
• Anti-clogging PTFE ring junction
• 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.
• The electrode uses a standard BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is built-in. Users need to have a separate temperature probe to enable ATC or manually input temperature to realize temperature compensation.
