ETS-Lindgren's Model HI-3627’s ELF Magnetic Field Meter quickly determines ELF magnetic field distributions in various applications, such as power-line emissions, home ambient environments and high current factory locations. A data logger or chart recorder can be connected to the HI-3627 output to monitor field variations over time. Signals from three orthogonal sensing elements are combined in a vector sum to provide accurate magnetic field measurements from any ELF magnetic field source.
The 2kHz upper cutoff frequency enables accurate measurements of more than 30 harmonics of a 60 Hz power frequency field. The switch-selectable, lower frequency cutoff point enables testing to Swedish MPR and IEEE 1140 guidelines.
