(More customer reviews)works fine. I'm using magnets for pain therapy, and sometimes just wasn't sure I was applying the right pole. this device helped. shipping was very on time, nicely wrapped. I would recommend it.

How does it identify the north and south poles of a permanent magnet?Simply press and hold the black oval button.Then, place the tip of the detector near the surface of themagnet.If it is the North Pole, the Red LED will glow.If it's the South Pole, the Green LED will glow.It's just that simple.And if the button is held and the unit is moved around thesurface of the magnet....you can see the transition from onepole to another.This pole identifier is guaranteed to be 100% accurate.It can be used for rare earth magnets such as neodymium magnets, SmCo magnets, AlNiCo magnets, Ceramic magnets, refrigerator magnets and most other magnets.Applications? Pole detection of permanent magnets? Measurement of stray magnetic fields in packaging? Coil testing? Post-magnetization polarity checksHelps with the following tasks: ? Electric motor assembly ? Installation of magnetic clamping blocks ? Error Analysis ? Multipole quality control ? Pole detection of therapy magnetsDimensions: approx. 5.6" x 0.9" x 0.8", measuring side 1/2" x 1/2"Weight: approx. 0.08 lb with batteriesDisplay: two LED display (green= south, red=north)Sensitivity: ±17mT (170Gs) on/off hysteresisOperating temperature range: -10°C ~ +50°CStorage temperature: -20°C ~ +70°CBattery: 4 x 1.5v button cells (included)
