Testing apparatus for testing electrical and mechanical properties of e.g. paint, has receiver receiving media to be tested, where media include electrostatic field and apparatus includes light source, sensing unit and displaying unit

摘要

The apparatus has a sample receiver (1) receiving media to be tested, where the media include an electrostatic field and the apparatus includes a light source, a sensing unit and an optical displaying unit i.e. oscilloscope. The receiver is made of a translucent material selected from glasses and a plastic material and comprises an angular shape e.g. square shape. Electrodes (2, 3) of a high voltage unit (4) are arranged on sides of the receiver, where the sides lie opposite to each other. A polarization unit and/or a spectrometric unit is arranged between the receiver and the sensing unit. An independent claim is also included for a method for testing electrical and mechanical properties of liquid media.
