MULTIFUNCTION METER UT18C VOLTAGE TESTER UNI-T Universal AC/DC voltage meter with LCD display and LED indicator. With RCD test and phase sequence test The UT-18C meter allows you to measure DC and AC voltage in the range from 12 to 690V with automatic range change. It is equipped with two types of value information measured voltage: LED and LCD display. For DC voltages, it additionally informs about voltage polarity. In addition to measuring voltages, the meter can be used to check the continuity of the circuit, test the phase sequence and test the residual current circuit breakers.
