LEAD ION ELECTRODE INSTRUCTION MANUAL GENERAL INSTRUCTIONS Introduction Eutech Instruments Lead Ion Electrode is used to measure lead or sulfate ions in aqueous solutions quickly, simply, accurately, and economically. Required Equipment 1. 2. A pH/mV meter or an ion meter, either line operated or portable. Semi-logarithmic 4-cycle graph paper for preparing calibration curves when using the meter in the mV mode. Linear graph paper is recommended for low level measurements or lead/sulfate titration. A magnetic stirrer. Eutech Lead Ion Combination Epoxy-body Electrode, Code no. EC-PB-03. Lab-ware made of plastic, not glass, for all low level measurements. Polishing Paper, Code no. EC-MIS-PP, to polish dirty or etched electrode membranes. 3. 4. 6. 7. Required Solutions 1. 2. Deionized or d ...
