The HK235C Two-Pole Voltage and Continuity Tester is designed for fast electrical safety checks in residential, commercial and industrial installations. It combines a stepped LED voltage indicator with an LCD numerical display, allowing technicians to recognize standard voltage levels at a glance while viewing a more detailed measurement.
The tester covers 1-1000V AC and 1-1000V DC through the LCD, with LED indication at commonly used voltage steps. Optical and acoustic continuity feedback helps locate open circuits, damaged wiring and incomplete connections. For three-phase work, the HK235C includes phase-sequence testing, single-pole voltage detection and a 30mA RCD trip-test function.
A polarity indicator, automatic voltage self-test, vibration alert and silent operating mode make the instrument adaptable to different working environments. Its IP65 enclosure and CAT III 1000V / CAT IV 600V rating support field use around distribution systems and electrical service equipment.
