About

The BHC-2 and BHC-2RF are 78mm single axis Helmholtz coils. The BHC-2 model is ideal for DC and low frequency operation, while the BHC-2RF is specifically designed for AC operation. These coils are used to generate a magnetic field for calibrating sensors and meters, making them suitable for various applications including the creation of a known magnetic environment. Key features include a maximum field strength of 420μT and a 78mm mean electrical diameter. A probe holder kit is available, with STEP files provided for its construction.
