UNI-T UT18D Voltage and Continuity Tester

Description

UNI-T UT18D Voltage and Continuity Tester The UNI-T UT18D Voltage & Continuity Tester is a professional-grade electrical tester designed for electricians, maintenance technicians, and industrial users. It quickly tests AC/DC voltage, continuity, polarity, phase rotation, and RCD operation while providing a large backlit LCD display for easy reading. Rated CAT III 690V and CAT IV 600V with an IP65 dust- and water-resistant enclosure, the UT18D is built for demanding environments. Additional features such as single-lead voltage detection, continuity buzzer, work light, polarity indication, and automatic self-test make it an essential diagnostic tool for electrical installation and maintenance. Features: RCD Test Operating voltage of 230V (50Hz to 400Hz) Polarity Detection Positive & Negative Self-Inspection Full LED or LCD check Exceed Voltage Voltage range from 713V to 788V Auto Standby Power-saving mode with standby current < 10μA Silent Mode Functional across all ranges Work Light Built-in for low-light environments Low Battery Indication Triggers at around 2.5V Specifications: Parameter Value Voltage (V) – 6V 5V±1V Voltage (V) – 12V 8V±1V Voltage (V) – 24V 18V±2V Voltage (V) – 50V 38V±4V Voltage (V) – 120V 94V±8V Voltage (V) – 230V 180V±14V Voltage (V) – 400V 325V±15V Voltage (V) – 690V 562V±24V Phase Rotation Test 57Vac ~ 400Vac (3 phase), Frequency: 50Hz ~ 400Hz Single Lead (L2) Voltage Detection Operating Voltage: 100V ~ 690V, Frequency: 50Hz ~ 400Hz Continuity Test Resistance: 0Ω~100kΩ (+50% accuracy), Beeper and LED light indication RCD Test Operating Voltage: 230V (50Hz~400Hz) Polarity Detection Positive & Negative Self-Inspection All LED or LCD Voltage Indication LCD Exceed Voltage Voltage Range: 713V~788V Auto Standby Standby Current <10μA Silent Mode All Range Work Light Yes Low Battery Indication Around 2.5V LCD Backlight Yes LCD (Voltage) 6V~690V, ±(1.5%+5) LCD (Frequency) 40Hz~400Hz, ±(3%+5) IP65 Yes Power 1.5V Battery (R03) × 2 Display 73.5mm × 35.5mm Product Color Red and Grey Product Net Weight 280g Product Size (W x H x D) 272mm × 85mm × 31mm Standard Accessories Batteries Standard Individual Packing Blister, English Manual Standard Quantity per Carton 30pcs Standard Carton Measurement 440mm × 295mm × 455mm Standard Carton Gross Weight 17.5kg Applications: Electrical installation Residential wiring inspection Industrial electrical maintenance Three-phase system verification Distribution board troubleshooting Circuit continuity testing AC/DC voltage verification RCD safety testing Motor installation Electrical service and repair Package Includes: 1× UNI-T UT18D Voltage & Continuity Tester 1× English Manual Documents: Datasheet User Manual
