D-KHR Series - 5Kv & 6Kv - Digital Surge Tester

About the D-5KHR & D-6KHR

The Digital Surge Tester is designed for testing the coils and windings of low-range AC rotating machines up to 660V.
It integrates Surge Testing, DC Hi-Pot Testing, and Resistance Testing in one compact system.
With an embedded industrial PC, 8-inch touchscreen display, and advanced software for storing, recalling, and printing test reports, this unit is ideal for both workshop and in-field use.
