iMAR manufactures precise 3D magnetometers with integrated IMU already since a longer time. Now a new, iron-free, fully magnetic clean calibration facilities has been installed at the iMAR headquarters in St. Ingbert which allows an even more automated calibration of magnetometers, unaffected by any other magnetic distortions. 

This includes also an own designed 3D Helmholtz coil to apply well defined magnetic fields. The range covers even significantly stronger fields than the magnitude of earth magnetic field.
