The Magnetic Pole Identification Pen NS-1000 is a highly sensitive [approximately ±0.5mT (5Gs)], convenient, and quick tool for identifying magnetic field polarity.

Simply press the switch and bring the pen tip close to the object being measured to distinguish between the N pole or S pole. The red LED light indicates the "N" pole, and the green LED light indicates the "S" pole.

The detection results are very intuitive. The front end has a diameter of about 4mm, making it easy to detect small magnets.

l Technical Parameters

Sensitivity: Approximately ±0.5mT (5Gs).

Dimensions: Length 170mm, diameter 13.8mm, test front end diameter about 4mm.

Display: Red/N pole, Green/S pole

Usage Time: Approximately 10 hours or more of continuous identification (N/S pole LED lights on)

Battery: 2 AAA 1.5V, size 7 batteries

Weight: Approximately 100g

Operating Temperature: -20℃ to +80℃

l Instructions for Use

1. Press the power switch button, and the N and S LED lights will flash. (Keep away from magnets when turning on.)

2. When measuring the magnetic pole of a magnet, bring the front end close to the object to accurately identify the N/S polarity.

3. Red represents the N pole, green represents the S pole.

4. Please turn off the power when not in use.

5. If the device is turned on but not used for 10 minutes, the system will automatically power off. To use it again, turn it back on.

l Battery Replacement

1. Unscrew the switch part counterclockwise.

2. Remove the internal batteries and replace them with 2 AAA 1.5V, size 7 batteries (pay attention to the battery installation direction).

3. After installing the batteries, press the power switch to confirm if it is powered on.
