Pen Type Voltage Detector With Display ( HTC – AC IV )

Description

The HTC AC‑IV Non‑Contact Voltage Detector is a compact, pen-style tool designed for electricians, technicians, and safety-conscious DIY users, offering fast and accurate non-contact detection of live AC voltage in wiring, outlets, breakers, and junctions. With a detection range from 12 V to 1000 V AC in High‑Sensitivity mode and 48 V to 1000 V in Low‑Sensitivity mode, this versatile device effectively supports a wide variety of electrical environments—from household circuits to industrial panels.

Equipped with a multi-level bar‑graph LCD display, the HTC AC‑IV visually indicates proximity and voltage intensity. A built-in backlight with red and green double‑colour LED alerts the user to live (red) or neutral/safe (green) wires, helping differentiate conductors before contact. The device provides audible beeping and flashing visual cues when voltage is detected, making it simple to use even in noisy or dim work conditions.

With a slim, lightweight design—measuring approximately 157 × 27 × 23 mm and weighing under 40 g—the AC‑IV comfortably clips to a pocket or slips into a tool belt for quick access. Powered by two AAA batteries, it features auto power‑off after about 3 minutes to conserve battery life and includes a low‑battery indicator to avoid unexpected downtime.

Safety is paramount with the HTC AC‑IV. It is rated CAT III 1000 V, meaning it meets high safety standards for industrial and commercial testing on distribution circuits and branch panels. The housing carries an IP40 dust-resistant rating, and the tip is insulated to protect users during use.

Operation is straightforward—simply bring the probe tip close to a live conductor or outlet. Detection of AC voltage triggers both visual (bar-graph intensity, red LED) and audible alarms. The multi-sensitivity modes adapt to different voltages: in High mode, it detects down to ~12 V; in Low mode, the floor is ~48 V, allowing selective detection in environments with stray or ghost voltages.

The HTC AC‑IV also includes a built-in flashlight, activated automatically when voltage is detected or when operating in darker environments—a helpful feature when inspecting wiring in confined or poorly lit areas.

Field professionals benefit from its robust yet ergonomic build: the solid plastic housing is easy to grip and remains comfortable during one-handed operation. The device is also shock‑resistant enough for daily use in panel interiors and live installation testing.

Typical applications include verifying that wiring is de-energized before repair, identifying live versus neutral conductors in wall cavities or switchboards, checking live status of feeders and outlets, detecting energized lines inside conduits, and evaluating circuitry in distribution or switchgear systems. Its broad voltage range and sensitivity controls also make it useful for detecting both standard Mains power and lower-voltage control circuits.
