Measure AC/DC magnetic fields in electric transmission equipment, power lines, microwaves, air conditioners, refrigerators, monitors, video/audio devices and other electrical equipment with the Extech MF100!

Equipped with a Hall effect sensor with ATC (automatic temperature compensation), the Extech MF100 can measure magnetic fields in both Gauss and mT (milli Tesla) with range of up to 3000mT (DC), 1500mT (AC), 30,000G (DC) and 15,000g (AC). A zeroing button is included for use with DC measurements.

Alongside a reading of the magnetic field the MF100 will also indicate north pole or south pole on the display. Built-in MIN/MAX and data hold functions are also included.
