For measurement of static electric fields with CASSY (
524 013,
524 006,
524 005W2,
524 018) or universal physics measuring instrument (
531 835). The field is recorded with the correct polarity. To be used for example in experiments for field strength in capacitors, with or without dielectrics, or for field strength of charged bodies. For investigation of the electric field of the earth's ionosphere (approx. +100 V/m) and the electric charge of clouds (some kV/m). With the 1-cm voltage measuring plate (included), it can be used as an extremely high-impedance voltmeter, e.g. for potential measurement in a free space by potential probe or with Faraday’s cup.
