Apera Instruments AI3157 Stainless Steel Spear pH Electrode for Solid Food Samples

Features:

• Spear sensor designed for direct pH test of food samples such as cheese, fruits, dough, sushi rice, and meat products
• LabSen S-type glass membrane, featuring fast response and high firmness
• Open&Ceramic double-junction with Polymer electrolyte
• Long-Life Reference System - improves the stability of the reference and extends the electrode's service life
• Food-grade titanium housing
• Built with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 751 Titanium-body pH Electrode is designed for food samples such as cheese, fruits, dough, sushi rice, and meat products.
• 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 when inserting into food samples.
• Open&Ceramic double-junction with Polymer electrolyte - ensures full contact with test samples while minimizing junction clogs. No need to refill electrolytes.
• 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 electrode 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 achieve temperature compensation.
