Voltage Tester LIMIT 112 (model 144890209) — handheld non-contact voltage detector

Handheld voltage tester LIMIT 112 is a compact non-contact voltage detector designed to indicate the presence of alternating current (AC) voltage in conductors, sockets and electrical installations. The device detects electromagnetic fields generated by live conductors and provides clear visual and/or acoustic indication when voltage is present. Battery-powered and lightweight, the LIMIT 112 is intended for quick safety checks and basic troubleshooting tasks by electricians, technicians and DIY users.

Advantages

The LIMIT 112 offers fast, non-contact voltage detection without the need to expose conductors, reducing risk during preliminary inspections. Its compact size and battery operation make it portable and convenient for on-site checks. The combination of visual and acoustic signals ensures detection in various environments and lighting conditions. The tester is suitable for use on a range of common AC circuits and outlet types found in residential and commercial settings.

Suitable for

• Quick checks of live/non-live status of cables and wires
• Testing sockets and wall outlets for presence of AC voltage
• Preliminary verification of circuits before maintenance or repair
• Basic electrical troubleshooting in homes, offices and light commercial installations

Key specifications

• Type: handheld non-contact voltage detector
• Detection method: capacitive/inductive sensing of AC electromagnetic fields
• Power supply: battery-powered for portable use
• Indication: visual LED and acoustic signal for voltage detection
• Form factor: compact, pen-like design for access to confined spaces

How to use

Before use, ensure the tester battery is installed and the device is functional by following any included self-test procedure. Hold the tester near the insulated conductor, socket or terminal to be checked without making metallic contact. Move the sensing tip along the cable or approach the outlet face; the tester will indicate the presence of AC voltage with light and/or sound when a live conductor is within its detection range. After testing, remove the tester from the work area and switch it off, or follow the device’s automatic shut-off if provided.

Usage recommendations

Use the LIMIT 112 as a preliminary verification tool only. Do not rely solely on a non-contact tester for definitive absence of voltage when performing live work—verify with a suitable contact meter or follow established safety procedures and local regulations. Replace batteries as needed and inspect the tester for damage before each use.
