Uni-T UT18D voltage and continuity tester

The Uni-T UT18D is the most feature-rich voltage and continuity tester in the UT18 series, designed for diagnosing electrical installations in demanding operating conditions. The device allows for AC/DC voltage measurement in the range of 6 V to 690 V, frequency measurement from 40 Hz to 400 Hz, circuit continuity testing with audible and LED indicators, detection of positive and negative polarity, phase sequence testing, and voltage detection with a single probe. The model is equipped with a large, backlit LCD display measuring 73.5 × 35.5 mm, which improves the readability of results, while additional features such as RCD testing, self-test, silent mode, auto-standby, flashlight, and low-battery indicator streamline daily installation and maintenance work. The robust construction, compliant with IP65 and CAT IV 600 V, ensures high durability and safety of use.

A gloved hand holds a tester with a digital display, measuring parameters in an electrical switchgear.

Included

  • Voltage and continuity tester
  • 2 AAA batteries
