    Beskrivelse

    Oversættelse igang. Lige nu arbejder vi på at oversætte dette produkt fra engelsk til dansk. Kontakt os så frem du har brug for hjælp.

    Experiment Topics:

    • Measurement at galvanic voltage sources
    • Daniell cell, series and parallel circuits
    • Electrochemical potentials (voltage sequence)
    • Determination of the standard potentials of different metals and non metals
    • How potentials depend on concentration
    • How potentials depend on temperature
    • Charge and discharge of a steel accumulator
    • Leclanché cell
    • Measurement of pH values
       

    A complete equipment set in a case for basic experiments on electrochemistry.
    A cell block made of tough plastic, which can be unscrewed into two halves for ease of cleaning, allows four galvanic cells to be connected in parallel. A piece of filter paper stretched between the two halves of the cell acts as a diaphragm.
    Includes a handy, high-resistance meter for measuring potential differences with very little current and measuring pH values with the help of the supplied pH measuring probe.
