Diameter 10mm. 7. R217 double salt bridge saturated calomel electrode. This electrode is a measuring element that plays a reference role in pH electrode, ion meter and other analytical instruments. It forms a battery with various indicator electrodes, which can measure various ion concentrations in aqueous solution and carry out potentiometric titration analysis. Internal resistance K: ¡Â 10 Comparison potential MV: ± 3 Circulation of fluid network part: ¡Â 0.05 Salt bridge solution: saturated KCl Use, maintenance and precautions A. When the electrode is used, the rubber plug and rubber cap of the hole at the upper and lower ends of the electrode should be pulled out to prevent the diffusion potential from affecting the test results. B. There should be no bubbles in the salt bridge solution in the electrode to prevent the solution from short circuit. The electrode of saturated salt bridge solution model should retain a little crystal to ensure the saturation requirements. C. When using the double salt bridge electrode, the rubber plug and rubber cap must be used. In the second section, the salt bridge solution is put into the appropriate inert electrolyte solution, and then it is put into use to ensure the accuracy of the test results. D. When there is salt bridge solution or crystal on the electrode shell, it should be removed at any time. 8, r151 mercurous sulfate electrode R151 mercury / mercurous sulfate electrode) and pH electrode glass electrode, ion selective electrode and metal electrode form electrode pair, which is used for measuring pH value and ion concentration value of solution or for potentiometric titration analysis Technical indicators: Model: r151 Structure type: Mercury / mercurous sulfate Potential deviation from standard calomel electrode (MV. 25 °): 656 ± 3 Electrode internal resistance: ¡Â 10 Boundary dimension (mm): diameter 6 × 150 mm Features: single salt bridge porous ceramic liquid interface Self salt bridge solution: saturated potassium sulfate solution General use: as reference electrode (acid medium) Note: due to the large negative temperature coefficient and thermal hysteresis of the electrode potential of mercurous sulfate, the temperature fluctuation of mercurous sulfate electrode should be prevented as much as possible during the measurement, and the electrode should be kept constant temperature during the accurate measurement. Mercurous sulfate electrode is generally not suitable for use in the environment above 70 "C. 9. R218 silver chloride reference electrode Product model: R218 Product features: silver silver chloride electrode The outer diameter of silver electrode glass is about 6mm, and the reference solution is filled with saturated potassium chloride solution in the factory. Standard electrode potential of Ag AgCl electrode / V (for NH Silver / AgCl electrode: Advantages: easy to prepare, stable potential, good reproducibility, solid electrode structure, small temperature hysteresis, can be used at high temperature Disadvantages: the solubility of silver / AgCl electrode in the concentrated KCl solution is relatively large, and AgCl should be added to the external reference solution first to pre saturate, otherwise the AgCl coating of the reference electrode will be dissolved, making the potential unstable.
