Thin Film Volume Resistivity Measurement Instrument

The film volume resistivity tester measures the resistance per unit volume of thin film materials by applying a DC voltage. The instrument employs the four-probe method or three-electrode method to record current and voltage data under standard temperature and humidity conditions, and calculates the volume resistivity accordingly. It is used to evaluate the insulation properties of thin film materials such as plastics and coatings, with applications in electronic component packaging and cable insulation layer testing.
Selection
When selecting, ensure the measurement range covers 10^6-10^18 Ω·cm, with an accuracy error of less than ±5%. It must be compatible with material thickness and support the four-probe or three-electrode method. Check the temperature and humidity control functions to ensure compliance with ASTM D257 standards. Consider the adaptability of the sample fixture, ensuring the electrode material is made of oxidation-resistant metal. The instrument should include automatic polarization compensation and a data export interface.
