specifications Product Name: Electrician Multi functional Sound and Light Alarm Number Display Verification Pen Packaging size: 17 × 3 cm ≈ 6.69 × 1.22 in Description: Accurate detection: It can accurately detect the presence of AC voltage without direct contact with wires to complete the measurement. This non-contact design not only improves work efficiency, but also greatly enhances operational safety and avoids the risk of electric shock. Digital display function: Equipped with a high-precision LCD screen, it can display measurement results in real time, including specific values of AC voltage. The digital display method makes reading data more convenient and efficient, avoiding the errors that may occur with traditional pointer instruments and ensuring the accuracy of measurement results. Double prompt: When voltage is detected, the measuring pen will emit bright lights and clear beeps, providing a dual warning. This design is particularly practical in low light or noisy work environments, ensuring that operators can promptly detect potential electrical issues and take appropriate safety measures. Powerful function: In addition to the basic voltage detection function, this measuring pen also has the function of searching for zero and hot wire breakpoints. Through intelligent sensing technology, the breakpoint position in the circuit can be quickly located, helping electricians to quickly troubleshoot, improve maintenance efficiency, and save time and energy. Portable design: The compact and lightweight design makes it easy to carry and store, suitable for various work environments. Whether it is household electricity inspection, construction site construction, or professional electrician maintenance, this multifunctional measuring pen can play an important role and become an indispensable assistant for electricians.
