The Extech MF100 is a handheld magnetic field meter designed to accurately measure both AC and DC magnetic fields in Gauss and milliTesla (mT). Equipped with a uniaxial Hall effect sensor featuring Automatic Temperature Compensation (ATC), it ensures stable and reliable readings across varying environmental conditions. The meter clearly indicates magnetic polarity (North or South pole) for DC fields and includes practical functions such as Zero, Data Hold, Min/Max, and auto power-off—making it ideal for use in industrial settings, research laboratories, and consumer electronics testing.
