About
This system is the perfect companion to Bartington Instruments’ Helmholtz Coils (HC1, HC2 and HC16). It includes the PA1 Power Amplifier, CU1 Control Unit, and CU2 Closed-Loop Module. LabView™-based control software is also supplied to provide a turnkey Helmholtz Coil System. Key features include a field strength of ±1mT from DC to 440Hz, active compensation using the CU2, and orthogonality correction using the PA1. Applications for this system include directional tool calibration, reference magnetometry, compass and magnetometer calibration, and biomagnetics.
