Unique LabSen semi-micro cylindrical glass membrane (6mm in diameter) makes small-sample pH testing easier than ever, and can be tested in high temperature samples (up to 212˚F). 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 temperature changes. It improves the stability of reference electrode and prolong the service life of the electrode. Housing Material: Lead-free glass; Temp. Sensor: No; Junction: Ceramic; Reference: Long-Life; Electrolyte: 3M KCL; Length: 150mm; Diameter: 12-6mm; Membrane Shape: Cylindrical; 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 sockets. Temperature sensor is not built-in. Users need to have a separate temperature probe to achieve automatic temperature compensation or manually input temperature to achieve temperature compensation. The product is CE and RoHS certified, and is manufactured under an ISO 9001: 2015 certified quality system.
