Wire and Live Voltage Detector DPM V31 — detects AC live wires, metal and wood contact

The DPM V31 handheld wire and live voltage detector is a compact, non-invasive tool designed to locate AC live wires and to sense the presence of nearby metal and wood. It provides preliminary detection of live voltage without direct contact and helps identify conductive or wooden structures behind surfaces during wiring inspections, renovations, and installations. Its small size and portability make it practical for electricians and DIY users who need a quick, on-site check for live circuits and hidden structural elements.

Advantages

The detector combines live-voltage sensing with metal and wood detection in a single handheld device, enabling multiple checks without switching tools. Non-invasive operation reduces the need to open walls or panels for initial assessment, which saves time during troubleshooting and planning. The unit’s compact design and intuitive controls support fast scanning in confined spaces and on various surfaces. Visual and acoustic indicators deliver clear, immediate feedback on detected voltage or nearby objects.

Suitable for

• Quick identification of live AC wires behind walls, ceilings, and outlets
• Locating metal studs, pipes, and electrical boxes during renovations
• Detecting wooden beams and joists prior to drilling or cutting
• Pre-checks of circuits before carrying out electrical work
• General troubleshooting and site inspections by electricians and DIY users

Key specifications

• Detection modes: AC live voltage detection, metal detection, wood detection
• Operation: non-contact sensing through common building materials
• Form factor: handheld, lightweight and portable
• Indicators: visual LED indicators and acoustic signal for detection feedback
• Typical working range: suitable for locating conductors and structural elements behind drywall and similar materials
• Power source: battery powered for cordless use

How to use

Switch the detector on and select the appropriate detection mode for the task: live voltage, metal, or wood. Hold the detector close to the surface to be scanned and move it slowly and steadily across the area. Observe the visual indicators and listen for acoustic signals to determine the presence and approximate location of live conductors or structural elements. For voltage checks, approach outlets, switches and junction boxes from multiple directions to verify readings. Turn the device off after use and remove the battery if long-term storage is planned.

Usage recommendations

Use the DPM V31 as a preliminary, non-contact detection tool only. Always verify any detected live voltage or buried conductor with a suitable contact voltage tester or multimeter before performing work. Do not rely solely on non-contact detection for safety-critical decisions. Follow applicable electrical safety practices and local regulations when working on or near live circuits.
