Check the listing for details. Multi-Field EMF Meter AF-3500: RF Strength/ Electromagnetic Radiation Detector. Condition: New. Listed at 149.99 USD. The LATNEX® AF-3500 Multi-Field EMF Meter is a Semi-professional but small and compact device that can measure electromagnetic field (3-axis), electric field, and RF strength. The AF-3500 measures high-frequency electromagnetic fields (RF) in a frequency range of 50MHz - 3.5GHz and low frequency electric and magnetic fields (EMF) at 50-60Hz.Magnetic field strength is measured in milliGauss (mG) and microTesla (μT) for 3 axis X, Y, and Z.Electric field strength is measured in volt per meter (V/m).RF field strength is measured in millivolt per meter (mV/m).A 2 inch color TFT LCD screen displays the 3 results clearly all at the same time, with also the option to hold the 3 results.Features:- 4 digits, 2.4 inches color TFT LCD - 3 measurements in one meter: Electromagnetic Field ( 3 - axis ).
