Coating Film Resistivity Tester

The paint film resistivity tester applies a DC voltage to the electrode in contact with the coating surface and measures the current value. The resistivity is calculated according to Ohm's law. It is used to evaluate the insulation performance and conductivity uniformity of coatings, and to detect quality in scenarios such as automotive electrophoretic paint and insulation coatings for electronic components.
Selection
When selecting, consider that the measurement range should cover the actual resistance value of the coating, the electrode material should be compatible with the surface being measured, and the test voltage should be adjustable to meet standard requirements. Pay attention to the temperature and humidity compensation function to ensure data stability. The instrument should come with a calibration certificate and feature protective design suitable for laboratory environments.
