Product OverviewThe UNI-T UT12D is a professional, pen-style non-contact AC voltage detector designed for safe and efficient electrical troubleshooting. It allows users to quickly verify the presence of live voltage in conductors, cables, sockets, and electrical panels without needing to make direct physical contact. With its dual-mode sensitivity, it is a versatile tool for electricians, maintenance technicians, and power system students who need a reliable, "carry-everywhere" safety device for verifying circuit status. Key FeaturesDual-Mode Sensitivity: Features a selectable High/Low mode to suit different applications: High Mode (90V–1000V): Designed for standard residential and industrial power systems (e.g., distribution boards, circuit breakers). Low Mode (24V–1000V): Highly sensitive, ideal for troubleshooting lower-voltage systems like control circuits, HVAC signals, or audio equipment.Non-Contact Safety: Uses electromagnetic induction to detect voltage, allowing you to check for live wires safely through insulation or behind panels.Acousto-Optic Alerts: Provides immediate feedback with both a high-intensity buzzer and a flashing LED indicator when voltage is detected. Integrated Utility: Includes a bright, built-in LED flashlight for working in dark cabinets or under-panel environments. Robust Field Design: Rated CAT IV 1000V for high safety standards and designed to withstand a 1-meter drop. Energy Management: Equipped with an auto-power-off function (after 5 minutes of inactivity) to conserve battery life.
