The Professional Magnetic Voltage Detector
Electricians face hidden electrical dangers daily. Therefore, UNI-T introduces the UT12M Magnetic Voltage Detector. We engineered this professional non-contact pen to identify live AC voltages safely. Consequently, you can troubleshoot complex circuits and magnetic components without touching bare wires.
🛡️
Smart Non-Contact Safety
We prioritize your safety above all else. This tool utilizes a highly sensitive NCV inductive probe. Specifically, the tip glows bright red and beeps rapidly when it approaches a live electrical source. Therefore, you stay completely safe during inspections.
🧲
Advanced Magnetic Flux Induction
The UT12M model features a unique magnetic flux induction function. You can easily detect the presence of magnetic fields in industrial components. As a result, it is perfect for diagnosing faulty solenoid valves, relays, and contactors quickly.
⚡
Dual AC Voltage Modes
Electrical systems operate at various power levels. Consequently, we programmed this device with dual ranges. The low mode handles 24V-1000V for sensitive electronics. Conversely, the high mode manages 90V-1000V for heavy-duty distribution panels.
💡
Built-In Flashlight & Auto-Off
Dimly lit environments make electrical work incredibly dangerous. Therefore, we integrated a bright LED flashlight directly into the testing tip. Furthermore, the device powers off automatically after five minutes of inactivity to preserve battery life.
💡
Tech Insight: Prioritize Workplace Safety
Solenoid valves, relays, and exposed terminals pose severe shock hazards in industrial environments. When diagnosing these components, maintaining a safe distance is absolutely critical for preventing workplace injuries.
By using a Magnetic Voltage Detector, you instantly verify magnetic fields and live currents without making physical contact. To master electrical safety and proper testing protocols, we highly recommend reviewing the official guidelines provided by the Occupational Safety and Health Administration (OSHA).

Product guides and documents
UT12SDEM User Manual (PDF)FAQs
Q1: What is the main difference between the UT12M and the UT12E?
A: The UT12M is equipped with a unique magnetic flux induction sensor, making it ideal for testing relays and solenoid valves. In contrast, the UT12E features a vibration motor, which is better suited for extremely noisy industrial environments where you might miss audio alerts.
Q2: How do I use the magnetic flux detection feature?
A: Simply turn on the device and bring the tip close to a working solenoid valve, relay, or contactor. If a magnetic field is present (meaning the internal coil is functioning properly), a yellow LED indicator on the pen will light up.
Q3: Do I need to strip the wire insulation to test for live voltage?
A: No, you do not. This is a non-contact Magnetic Voltage Detector. It can safely detect the presence of AC voltage right through the plastic insulation of power cords, outlets, and terminal strips.
Q4: Is the low voltage mode safe for testing household outlets?
A: Yes. However, for standard 110V/220V household outlets, you should use the High Voltage Mode (90V-1000V). The Low Voltage Mode (24V-1000V) is highly sensitive and is specifically designed for testing low-power audio systems, thick cables, and weak electromagnetic signals.
