Test Equipment Description

Helmholtz coil is designed to produce standard magnetic field with wide applications. It can be used to calibrate Hall probe and different types of magnetometers, compensate geomagnetic field, judge magnetic shielding effect, measure radiated magnetic field and research material magnetic properties. It is featured with open space, easy to use, good linearity between magnetic field and supply current and broad uniform area for magnetic space. It can meet the requirements of IEC61000-4-8, GB/T17626.8, GB/T17215-2002 and GB/T15283-94. One-dimension, two-dimension and three-dimension combined magnetic field can be made according to needs.
