Featuring a dual LED display for easy reading, it operates in extreme temperatures and boasts a long battery life, making it ideal for professionals in various fields. ## Description Induction value: 0.005 tesla = 5 mT, Sensitivity: ± 5mT. Applications:Pole detection of permanent and electro magnets.Post-magnetization polarity checks.Coil testing.Assistance with the following tasks:electric motor assembly,installation of magnetic clamping blocks, error analysis, multipole quality control. Press and hold the oval button shown on the photo below. Then place the tip of the detector to the surface of the magnet.Sensitive area 6 * 3mm. Display: 2 LED display，(green = S pole, red = N pole),If it is the "N" Pole,the Red LED will shine, if it's the "S" pole, the Green LED wil light. If surface of the magnet, ome can mote the transition from onE pole to another. Use battery: 1X1.5V LR03 AAA battery （ included）(continuous use time > 10 hours). Size: about 140 * 20 * 19mm,Sensitive area 6 * 3mm. ## Features - Induction value: 0.005 tesla = 5 mT, Sensitivity: ± 5mT. - Applications:Pole detection of permanent and electro magnets.Post-magnetization polarity checks.Coil testing.Assistance with the following tasks:electric motor assembly,installation of magnetic clamping blocks, error analysis, multipole quality control. - Press and hold the oval button shown on the photo below.
