About This

• Easy Operation: One-button design makes polarity testing simple and intuitive—just press and hold the button while touching the magnet surface; red LED lights up for North pole, green for , eliminating guesswork in seconds.
• Compact Design: Pen-shaped tester measures only 6.06 x 1.06 x 0.94 inches and weighs just 2.27 oz, fitting comfortably in hand or pocket for on-the-go use in labs, workshops, e on, or field service.
• Clear Visual Feedback: Dual-color LED indicators provide immediate, unambiguous polarity confirmation—no reading charts or interpreting values, ideal for technicians, students, and hobbyists verifying magnet orientation or coil winding direction.
• Broad Compatibility: Works with permanent magnets, electromagnets, magnetic assemblies, and solenoid coils—ideal for magnetization checks, speaker magnet alignment, motor repair, and STEM classroom experiments.
• Reliable Performance: Engineered with ±5mT sensitivity and stable operation from -20°F to 176°F, powered by two standard AAA batteries (not included), delivering consistent results across industrial, e onal, and DIY applications.
