The dielectric constant tester is designed for testing materials such as insulating materials, PCB substrates, films, ceramics, and liquid media. It measures parameters including relative permittivity and dielectric loss tangent.

Performance Features:

1. Capable of measuring dielectric constant.

2. Utilizes variable-frequency technology to eliminate 50Hz power frequency interference, ensuring reliable data acquisition even in environments with strong electromagnetic interference.

3. Features over-current protection to prevent instrument damage in the event of a short circuit or dielectric breakdown of the test sample.

4. Includes grounding protection; the instrument will not operate if grounding is poor or absent.

5. Equipped with an internal standard capacitor and high-voltage power supply, facilitating on-site testing and minimizing external wiring.

6. Features a large LCD screen and simple operation, with Chinese-language menus guiding the testing process.

7. Displays corresponding wiring diagrams for each function interface, greatly simplifying the wiring process for the operator.

8. Supports switching between Chinese and English interfaces. 1 Operating Conditions: 15°C–40°C; RH < 80%
