Discharge Tube Arrester TesterDarui Electric recommendsPerformance FeaturesIt is 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 surge arresters. It can also be used as a stabilized voltage and constant current source for other applications.
Ø Features high-voltage short-circuit protection, overcurrent protection, high-voltage presetting, and range adjustment. High-voltage self-discharge time is less than 0.5 seconds.
Ø Self-test function.
Ø Measurement data displayed by 3½ LCD digital display, high accuracy, and good reliability.
Ø During measurement, the range can be preset, and an audible alarm is given for over-range testing, suitable for component grouping and inspection.
Ø Continuous measurement mode allows uninterrupted testing of batch samples.
Ø Simple panel functions for easy operation.
Ø Lightweight and portable.
