Magnet Polarity Tester Pen can be easily read at places hard to access or in the dark, and cannot be accidentally remagnetized by strong magnetic field pulses.
To identify a magnet polarity, you can use Magnet Polarity Tester Pen is an electronic Magnetic Polarity checker. The end of the device is put against the magnet face and the test button is pressed. The red LED lights up if the magnet face is a North Pole. The green LED lights up if the magnet face is a South Pole. The internal circuitry is based on Hall Effect Devices.
1. Simply press and hold the black oval button. place the tip of the detector near the magnet surface.
2. If it's the south pole, the green led will glow.
3. If it is the north pole, the red led will glow.
4. Used for electric motor assembly, coil testing, post-magnetization polarity checks.
