Holaday ELF Magnetic Field Meter Model 3627 Get Quote



Make isotropic measurements simply and economically with the Model 3627 three-axis ELF (extremely low frequency) magnetic field meter from Holaday Industries. Signals from the three orthogonal sensing colis combine in a vector sum to provide accurate magnetic field measurements from any ELF source, including single or polyphase electrical circuits, VDTs, household wiring and appliances. The unit's remote sensor and analog meter make quick work of finding ELF distributions in any application, and its wide dynamic range makes it an extremely flexible tool for measurements ranging from home ambient environments to high current factory locations
