It is a redox indicator electrode for potentiometric determination, determination of essential potentiometric titration and polarography, is also important raw chemical modified electrode electrode, has been widely applied in water quality monitoring, ecological environment, soil, sediment and metal corrosion research in chemistry and chemical engineering. Use and maintenance 1 Soak and rinse the electrode surface with water before use. A variety of measurements are availablePH/mV Meter used paired with calomel electrode or silver silver chloride electrode will be directly inserted into the sample, the potential stability of reading. 2 In situ determination of soil and sediment, especially the need to carefully, do not make the end deformation, surface, temporarily when not in use can be soaked into the water, not long dry box placed in the book. 3 The electrode, with long, surface oxide film or absorbent material, application0.2MHc1v1 -0.1MNac1 -0.2%Na2 SO3 The mixture is heated to70 CHandle2 Hours, and then saturated in hydroquinone hydroquinone0.05m Detection potential of potassium hydrogen phthalate two solutionE It should conform to the following formula: E=455 -0 .09 (t -25 )-[59.1+0.2 (t -25) PH Among them:PH by0.05 Potassium hydr
