Brand New Apera Instruments LabSen Glass-Body 851-1 pH Electrode for Viscous Solutions, Impact-Resistant Sensor, BNC Connector Manufacturer model: AI3110 Proprietary ph. sensor technology and materials from SwitzerlandUnique LabSen conical glass membrane, maximizing the sensor's surface area, making the pH test for viscous samples easier and more reliable.Silver Ion Trap Reference System + Proselyte reference solution, preventing the electrode being contaminated by proteins.Standard bnc connector6-Month fulfilled by Apera Instruments Description Backed by proprietary Swiss sensor technology and materials, Apera LabSen 851-1 Glass-body pH Electrode is designed for testing pH of cosmetics and other viscous samples. Silver Ion Trap Reference System+Protelyte Electrolyte prevents the junction from being blocked or contaminated by proteins. LabSen Conical Glass Membrane maximizes the sensor's surface area, making the testing in viscous samples easier and more reliable; built tough, highly-resistant to general impact (completely different from the traditional fragile glass bulb sensor). Housing Material: Lead-free glass; Temp. Sensor: No; Junction: Ceramic 3; Reference: Silver Ion Trap; Electrolyte: Protelyte; Length: 120mm; Diameter: 12mm; Membrane Shape: Conical; Range: 0-14 pH; Temp. Range: 0 to 100?C (32 to 212?F); Connector: BNC; Cable: 3 Ft. The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors. Temperature sensor is not built-in. Users need to have a separate temperature probe to enable ATC or manually input temperature to realize temperature compensation. The product is CE and RoHS certified, and is manufactured under an ISO 9001: 2015 certified quality system.
