Apera Instruments AI3103 LabSen 241-6 Professional Combination pH Electrode for Small Samples (>0.2 mL), BNC Connector, Lead-Free Glass

Backed by proprietary Swiss pH sensor technology and materials, the LabSen 241-6 Micro Combination pH Electrode is designed for small-volume samples (≥0.2ml). Unique Glass Membrane – The LabSen 241-6 pH electrode adopts a semi-micro cylindrical glass membrane (6mm in diameter), making 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 connectors. Temperature sensor is not built-in. Users need to have a separate temperature probe (ex: Apera MP500) to enable ATC or manually input temperature to realize temperature compensation. The electrode is backed up with a 6-month warranty by Apera Instruments.
