635 Tester BVD-1500

The capability of this tester extends up to 1200 AC / 1500 DC, covering voltage tests in both alternating and direct current, including three-phase voltage in alternating current. Additionally, it provides phase sequence indication in three-phase alternating current systems, residual current device (RCD) tests, electrical continuity, voltage detection without the need for battery power, as well as overvoltage and undervoltage alerts, among other functions. The integrated flashlight provides convenient illumination for using the tester in dark environments.
