Profile: Polytronic Corporation specializes in manufacturing and wholesaling a variety of magnetic instruments like magnetic measuring system, research electromagnet, laboratory electromagnet, digital meters, electromagnets & associated equipment, and magnetizer & calibrator equipment. Magnet calibrator is basically used for magnet charging as well as calibration. There is an impulse magnet charger and a half cycle pulse generator having variable frequency and variable amplitude/single shot facility. The instrument performs various applications in calibrating, aging, partially knocking down of field strength of a magnet assembly. Impulse magnet chargers act as energy storage capacitor discharge type magnet chargers. These find applications in electro motors, loudspeakers, and sensors. These are capable of charging various types of magnetic materials from Alnico, ferrites, and rare earths, in any intricate shape & size, from simple dipole to complex multi-poles. These are available in power capacities from 150 Joules to 30,000 Joules.
