Pen Electrode PH Sensor BNC Connector Probe Pool Water Factory Industry Experiment Laboratory pH Composite Electrode E-201OOTDTYOnscribement:Composite electrode and E-201C E-201PH composite formed by phelectrode and silver chloride reference electrode, is a polycarbonate shell, it is a pH meter measuring the key component for measuring aqueous solution of hydrogen ions at the depth of pH value, widely used in heme industry, Pharmaceutical industry and career research pH detection. Features:, When the PH electrode used for the first or long home without, activated 2 hourselectrode ball soaked in 3.3N potassium chloride solutionThe measurement should be washed in distilled water and wiped dry with filter paper to prevent contamination in the electrode bulb, and with the liquid should also be immersed in the test solution of the E-201 pH composite electrode, do not add outside the reference solution.
