PUNELE Magnetic Polarity Tester - Pen style LED indicator

1. Quick and easy magnetic identification: The magnet pole detector is designed for quick and simple identification of magnetic field polarities. This tool allows users to efficiently identify the north and south poles of magnets without needing complicated installations, making it suitable for both professionals and craft enthusiasts. 2. Portable and compact design: With a convenient pen style design, the north and south poles tester magnets are lightweight and compact and provide easy portability. It can be easily carried in your pocket or vehicle box, this allows you to measure anywhere without taking valuable space. 3. Accurate with advanced technology: Equipped with a accurate precision probe and a high performance chip, this magnetic polarity tester provides stable and accurate measurements. Advanced technology allows you to get accurate polarity readings every time by improving the quality and efficiency of your work. 4. Clear display with LED display: The magnetic pole identifier uses a clear LED indicator that displays the magnetic polarity with different colors, red for the north pole (n), and green for (s). This intuitive display allows rapid visual identification, allowing users to make informed decisions efficiently. Battery Powered: Two 1.5V AAA batteries (batteries not included), north and detector have a battery life of over 10 hours and ensure you can rely on for a long time without frequent replacement. This durability makes it a practical tool for long projects or tasks requiring long-term use. Approx. 10 hours Working temperature: -20 ° C +80 ° C Storage Temperature: -40 ° C +150 ° C How to Use: Press and hold the test button, then point the magnetic field identifying pen probe head at the end of the magnet to be tested until the light is illuminated. 2. During the detection process, if the red light is illuminated, the end of the tested magnet is N pole
