UNI-T UT18E voltage and continuity tester
The UNI-T UT18E voltage and continuity tester is a practical tool for quick diagnostics of electrical installations. It allows you to measure AC/DC voltages up to 1000 volts, check phase sequence, circuit continuity and the operation of residual current circuit breakers. It is convenient to use and at the same time provides clear readings both on the LCD display and with illuminated LEDs.

Universal voltage measurement range
The UT18E supports up to 8 voltage levels: 6V, 12V, 24V, 50V, 120V, 230V, 400V, 690V and 1000V. It operates on both AC and DC current, making it suitable for various types of installations - from domestic to industrial. The automatic polarity recognition function further helps to avoid errors when diagnosing DC circuits.

Continuity measurement and RCD testing
The tester allows you to check the continuity of a circuit in the range from 0 Ω to 60 kΩ, while the built-in sound signal and LED indicate that the current is flowing correctly. The UT18E also allows you to test residual current devices (RCD) at 230 V and 50-400 Hz, which increases the safety of use of the installation.

Additional functions that make work easier
The LCD display shows voltage in the range of 6-1000 V and frequency in the range of 40-400 Hz. The built-in flashlight, beeper, auto-off function and silent operation make the UT18E a convenient tool. The tester has an IP65 protection rating, which means it is dust and splash resistant - it will work well in construction and industrial conditions.
