MASTFUYI FY8851 Magnetic Polarity Tester N/S Pole Identify Tool North & South Magnetic Pole Identifier Magnet Detector - 1420

Operating instructions 1. Press and hold the test button, and align the probe head of the magnetic pole identification pen with the surface of the tested magnet until the signal light is on. 2. During the detection process, if the red signal light is on, it indicates that the surface of the tested magnet is n pole; if the green signal light is on, it indicates that the surface of the tested magnet is s pole. 3. Press and hold the test button, and make the probe head of the magnetic pole identification pen move along the surface of the tested magnet, then the process of the magnet changing from one magnetic pole to another can be observed. 7 battery Service temperature：-20℃～+80℃ Storage temperature：-40℃～+150℃ Size：6.14×0.95×0.78in weight：0.12lb Package included 1 x Magnetic pole pen 1 x Instruction manual 1 x Certificate 1 x Warranty card Magnetic pole identification pen is a fast, easy and safe tool, which is used to identify the polarity of magnetic field.
