Thin Film Volume Resistivity Tester

The film volume resistivity tester measures the resistivity per unit volume of thin-film materials by applying a direct current voltage. Its principle is based on Ohm's law, where the resistivity is calculated by detecting the current after the electrodes make contact with the sample. It is used to evaluate the insulating properties of materials such as plastics and coatings, and to control quality in the production of electronic component packaging and anti-static materials.
Selection
When selecting, consider that the measurement range should cover the material's resistance characteristics, the electrode configuration should be compatible with the film thickness, and the test voltage must match the material's withstand voltage value. Pay attention to the instrument's measurement accuracy and stability, ensure the operation interface aligns with user habits, and confirm that the environmental temperature and humidity compensation function is suitable for laboratory conditions. Verify the calibration certificate and after-sales support.
