HI-3637 VLF Magnetic Field Meter
​ETS-Lindgren's HI-3637 ​​VLF Magnetic Field Meter makes quick work of finding VLF magnetic field distributions in any application. 



​ETS-Lindgren's HI-3637 ​​VLF Magnetic Field Meter makes quick work of finding VLF magnetic field distributions in any application.  Its wide dynamic range makes the HI-3637 useful for measurement applications from VDT's and computer monitors to high current factory locations. Three orthogonal sensing coils are combined into a vector sum to provide accurate magnetic field measurements from any VLF magnetic source. Connect a data logger or chart recorder to the recorder output to monitor field variation. The frequency response meets both the Swedish and IEEE 1140 specifications for VDT testing​.
