The KDFC-2G varistor tester (lightning protection component tester) is suitable for measuring the DC parameters of overvoltage protection components such as zinc oxide lightning arresters (varistors), metal ceramic two - and three electrode discharge tubes, vacuum lightning tubes, etc. It can also be used as a voltage regulator, constant current power supply, and applied in other fields.

Product Name: Varistor Tester (Lightning Protection Component Tester), Lightning Protection Component Tester, Lightning Protection Component Measuring Instrument

1. The KDFC-2G varistor tester (lightning protection component tester) is suitable for measuring the DC parameters of overvoltage protection components such as zinc oxide lightning arresters (varistors), metal ceramic two - and three electrode discharge tubes, vacuum lightning tubes, etc. It can also be used as a voltage regulator, constant current power supply, and applied in other fields.

2. It has functions such as high voltage short-circuit protection, overcurrent protection, high voltage preset, and range adjustment, with a high voltage self discharge time of less than 0.5 seconds.

3. It has a self checking function.

4. The measurement data is displayed by a three and a half digit LCD digital display, with high accuracy and good reliability.

5. During measurement, the range can be pre-set and an audible prompt can be issued for exceeding the range during the measurement process, which is suitable for device grouping and inspection discrimination.

6. Choosing continuous measurement allows for uninterrupted testing of batch samples.

7. The panel has simple functions and is easy to operate.

8. Lightweight and easy to carry.
