Product Details

 Discharge Tube Tester / Discharge Tube Tester When measuring varistors, the DC/DC converter, driven by a certain high-frequency pulse, boosts the 12V DC voltage to the high DC voltage required for testing varistors.

When testing discharge tubes, the slope control circuit controls the DC/DC converter so that its output voltage rises from 20 to 1700V at a rate of 100V per second until the discharge tube discharges.

Detailed Introduction of Discharge Tube Tester 

Working Principle

When the discharge tube tester measures varistors, the DC/DC converter, driven by a certain high-frequency pulse, boosts the 12V DC voltage to the high DC voltage required for testing varistors.

When testing discharge tubes, the slope control circuit controls the DC/DC converter so that its output voltage rises from 20 to 1700V at a rate of 100V per second until the discharge tube discharges.

Scope of Application

Suitable for measuring the DC parameters of overvoltage protection components such as zinc oxide arresters (varistors), metal-ceramic two-electrode and three-electrode discharge tubes, and vacuum arresters.

● With high-voltage short-circuit protection, overcurrent protection, high-voltage presetting, range adjustment and other functions, the high-voltage self-discharge time is less than 0.5 seconds.

● With self-check function.

● The measurement data is displayed by 3 1/2 LCD digital display, with high accuracy and good reliability.

● During measurement, the range can be preset, and an audible alarm is issued for over-range testing during the measurement process, suitable for component grouping and inspection discrimination.

● Select continuous measurement to perform uninterrupted testing on batch samples.

● The panel functions are simple and easy to operate.

● Light weight and easy to carry.
