Product Description

Discharge Tube Tester

Darui Electric recommends for you

Product Features

1. Suitable for measuring DC parameters of overvoltage protection components such as zinc oxide arresters (varistors) and metal-ceramic two- and three-electrode discharge tubes. It can also be used as a stabilized voltage and constant current power supply for other applications.

2. Features high-voltage short-circuit protection, overcurrent protection, high-voltage presetting, range adjustment, etc. High-voltage self-discharge time is less than 0.5 seconds.

3. Self-test function.

4. Measurement data is displayed on a three-and-a-half-digit LCD with high accuracy and reliability.

5. During measurement, the range can be preset, and an audible alarm is given for over-range testing, suitable for component grouping and inspection.

6. Continuous measurement mode allows uninterrupted testing of batch samples.

7. Simple panel functions for easy operation.

8. Lightweight and portable.
