Handheld Magnetic Field Meter with N/S Polarity Display

Check a magnet's pole and compare local field readings while working at the bench. This handheld magnetic field meter displays polarity and field strength on its colour screen. It is for electronics hobbyists and workshop users examining magnets with the extended sensor tip.

• ✅ Identify which pole faces the sensor — The screen indicates north or south polarity.
• ✅ Compare magnets during a bench check — A numerical field reading makes changes visible as you reposition the tip.
• ✅ Reach the measuring point more easily — The narrow sensor extension projects beyond the display body.
• ✅ Take readings away from a computer — The built-in rechargeable battery powers standalone use.
• ✅ Set a reference before testing — Zero calibration and an adjustable no-field threshold are stated.

Move the sensor area towards the magnet and keep its orientation and distance consistent when comparing readings. Local field strength changes with positioning, so compare like-for-like setups rather than treating every reading as an intrinsic magnet rating.

The colour TFT screen shows field values in gauss and millitesla, alongside the pole indication. The compact circuit-board format has acrylic cover plates, three control buttons and a side power switch, keeping the controls visible during bench use.

The stated range is −3000 to +3000 gauss. A USB-C port is used for charging the built-in lithium battery, with USB data output also stated. A charging lead, mains adapter, test magnet and computer software package are not confirmed as included. This is a workshop measuring module, not an electrical-safety or medical instrument.
