Non-contact voltage tester UNI-TI UT12D-EU — AC 24V–1000V

The UNI-TI UT12D-EU is a non-contact voltage tester designed to detect AC voltage in the range from 24 V to 1000 V. The lightweight, handheld instrument identifies live conductors without requiring direct metal contact, enabling quick verification of outlets, cables and electrical panels. Its compact form factor and single-handed operation support rapid checks during maintenance, installation and troubleshooting tasks for both professional electricians and DIY users.

Advantages

The device provides fast voltage presence detection across a wide AC range, minimizing the need to expose conductors. Visual and audible indicators allow clear identification of live circuits even in confined spaces. Its non-contact operation reduces the risk of accidental short circuits and speeds up repetitive testing tasks. The tester’s compact size and low weight make it easy to carry and use for extended periods.

Suitable for

• Quick verification of wall outlets and socket circuits
• Identifying live wires in junction boxes and cable runs
• Checking voltage presence at distribution panels and breakers
• Routine electrical maintenance and troubleshooting
• DIY electrical checks in residential and light commercial settings

Key specifications

• Detection type: Non-contact AC voltage detection
• Voltage detection range: 24 V to 1000 V AC
• Indication: Visual LED and audible signal
• Operating method: Handheld, single-handed operation
• Power source: Battery powered (installed battery not specified)
• Design: Lightweight, pocket-sized housing for ease of carry

How to use

Hold the tester near the conductor, outlet or terminal to be tested and observe the visual and audible indicators. Approach the insulation or probe tip steadily; the device will indicate the presence of AC voltage within its specified range without requiring direct metal contact. Follow standard safety precautions by ensuring power sources are handled according to electrical safety rules and disconnecting circuits when necessary for more invasive work. Replace the battery as recommended by the manufacturer or when indications weaken.

Usage recommendations

Use the UNI-TI UT12D-EU as a preliminary check for voltage presence only. Do not rely on this tester as the sole means of verifying de-energised circuits for safe work. For confirmation of circuit state or when performing work on live systems, use suitable insulated tools and full electrical testing equipment, and follow applicable safety regulations and procedures.
