Apera LabSen 252 Manuals

LabSen 252 Glass Spear pH Electrode User Manual LabSen electrochemical sensors are premium pH electrode with manufacturing technology and key components imported from Switzerland. LabSen252 adopts spear type glass membrane, which can easily pierce solid or semi-solid medium. This electrode is suitable for cheese, meat, fruit and vegetable testing. This probe has following features: ⚫ Impact-resist membrane, there is no danger of electrode breakage during normal use. ⚫ Blue gel inner solution, does not flow and will not cause bubble. ⚫ Maintenance-free polymer electrolyte, non-diaphragm structure. ⚫ Long life reference system, has better stability and service life. 1 Technical Data Measuring Range (0 ~ 14) pH Electrolyte Polymer Temperature Range (0 ~ 80) °C Soaking Solution 3M KCl Shaft Material Lead-free Glass Electrode Dimension Electrode (Ø12×100) mm Measuring Tip (Ø6×35) mm Membrane Shape Tapered Reference Long Life Connector S7 Junction Ceramic+Single Pore Cable S7-BNC / Ø3×1m 2 Usage and Maintenance 2.1 Connect electrode to S7-BNC cable, and then connect BNC plug to the input on the pH meter. 2.2 When measuring, please unscrew the bottle cap, pull out the electrode and rinse it with deionized water. After using, please put the electrode back into the bottle and screw tight the cap. 2.3 After long time exposure in air, Polymer electrolyte will cause shrinkage. It will not happen in measurement status. The electrode must be soaked in 3M KCl solution for storage. After long time soaking, there will be some floccules dissolving out from 3M KCl solution, this is normal phenomenon. Before pulling out or putting back the electrode, make sure to fully loosen the blue cap on the storage sleeve so that the electrode can move in and out smoothly.
