Discharge Tube Tester
Darui Electric recommends for you:
Discharge Tube TesterPerformance Features:
l Suitable for measuring DC parameters of overvoltage protection components such as zinc oxide arresters (varistors), metal ceramic two- and three-electrode discharge tubes, and vacuum lightning arresters. It can also be used as a stabilized voltage or constant current power supply for other applications.
l Features high-voltage short-circuit protection, overcurrent protection, high-voltage presetting, and range adjustment. The high-voltage self-discharge time is less than 0.5 seconds.
l Has self-test function.
l Measurement data is displayed on a 3 1/2 LCD digital display, with high accuracy and good reliability.
l During measurement, the range can be preset, and an audible alarm is provided for over-range tests, suitable for component grouping and inspection.
l Continuous measurement mode allows uninterrupted testing of batch samples.
l Simple panel functions for easy operation.
l Lightweight and portable.
