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 Gal and electrolyte when temperature changes. It improves the stability of reference electrode and prolong the service life of the electrode. Polymer Electrolyte – The solid polymer electrolyte makes the electrode hard to be contaminated and maintenance-free. Special Glass Membrane – The Lab Sen 551 pH electrode adopts a spear sensor tip, which is ideal for directly testing semi-solid samples like soil. Housing Material: POM; Temp. Sensor: No; Junction: Ceramic Single Pore; Reference: Long-Life; Electrolyte: Polymer; Length: 90mm; Diameter: 15-6mm; Membrane Shape: Spear; Range: 0-14 pH; Temp. Range: 0 to 60˚C (32 to 140˚F); Connector: BNC; Cable: 3 Ft; electrode uses a BNC connector, and is compatible with any pH meters that use standard BNC sockets. 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.
