UNI-T UT12D / UT12E / UT12M Non-Contact Voltage Detector Pen – Dual Mode 24–1000V AC Tester

Imagine checking live wires, outlets, and switches in seconds – without ever touching bare metal. The UNI-T UT12 series non-contact voltage detector pens turn a risky guess into a clear, confident “yes or no” signal. With bright LEDs, audible alerts, and smart dual sensitivity modes, this pocket-sized tester helps homeowners, DIYers, and professionals stay safe while working around electricity.

⭐ Key Features & Benefits

• Non-contact, safer testing – Detect AC voltage through insulation without touching bare wires, reducing shock risk and giving you peace of mind.
• Wide AC voltage range – UT12D / UT12E / UT12M: 24–1000V AC; ideal for home outlets, lighting circuits, power strips, and appliances.
• High / Low dual sensitivity modes – Low mode (24–1000V, green indicator) for low-voltage circuits; High mode (90–1000V, red indicator) for standard mains power. Quickly adapt to different jobs without changing tools.
• Clear audio & visual alerts – A bright LED tip and buzzer increase in frequency as you move closer to live voltage, so you can “hear” and “see” danger even in noisy or dark spaces.
• Low battery indication – Know when it’s time to replace batteries so your readings stay reliable.
• Auto power-off – After about 5 minutes of inactivity, the pen turns itself off to save battery life – perfect for busy tool bags.
• Built-in flashlight – Illuminate dark panels, outlets, and corners so you can see exactly where you’re testing.
• Rugged, drop-proof design – UT12S / UT12D: tested to 1 m drops; UT12E / UT12M: tested to 2 m drops. Durable enough for job sites and everyday tool belts.
• Magnetic solenoid detection (UT12M) – Detect magnetic fields from solenoids and coils, adding extra versatility for HVAC and industrial work.
• Vibration alert mode (UT12E) – Feel a vibration when voltage is detected – ideal in loud environments where you might miss a beep.
• Professional safety ratings – CAT IV 1000V, ETL and CE certified, giving you confidence that this tester meets strict international safety standards.
• User-friendly design – Lightweight “electric pencil” shape feels like a pen in your hand, slips easily into a pocket, and is simple enough for beginners to use.
• Please note: Batteries are not included, so you can choose your preferred brand.

🔧 Perfect For

• Homeowners checking outlets, switches, and extension cords before repairs.
• DIY enthusiasts installing lights, fans, or smart home devices safely.
• Electricians and technicians needing a quick, reliable first-line voltage check.
