1. The magnetic pole identification pen is a fast, easy and safe tool. It is an instrument used to identify the polarity of a magnetic field.
2. It adopts a portable pen holder design, which is small and light, easy to carry, and can be measured anytime and anywhere without taking up space.
3. High accuracy sensitive probe and high performance chip make the measurement more sensitive and accurate.
4. It is easy to see, LED light emitting diodes will show their polarity in different colors, red is N pole, green is S pole.
5. Magnetic pole identification pen is powered by two AAA1.5V batteries, the use time is about 10 hours or more.

How to Use:
1. Press the TEST button, and aim the probe head of the magnetic pole identification pen on the of the measured magnet until the light is on.2. During the detection process, if the red light is on, it indicates that the of the measured magnet is N pole; if the green light is on, it indicates that the of the measured magnet is S pole.3 Press the TEST button and move the probe head of the magnetic pole identification pen along the of the measured magnet, you can observe the process of changing the magnet from one magnetic pole to another.
