Extech 480826 Triple Axis EMF Tester

EMF measurements are measurements of ambient (surrounding) electromagnetic fields that are performed using particular sensors or probes, such as EMF meters. These probes can be generally considered as antennas although with different characteristics. In fact probes should not perturb the electromagnetic field and must prevent coupling and reflection as much as possible in order to obtain precise results. There are two main types of EMF measurements:

  • Broadband measurements performed using a broadband probe, that is a device which senses any signal across a wide range of frequencies and is usually made with three independent diode detectors;
  • Frequency selective measurements in which the measurement system consists of a field antenna and a frequency selective receiver or spectrum analyzer allowing to monitor the frequency range of interest.

Ideal for testing the size of electromagnetic fields on fans, electrical appliances, wiring, power lines and more, the Extech 480826 is a three-axis EMF meter that can measure EMF input from X, Y and Z directions.

The meter is capable of measuring EMF levels in both μTesla (with ranges of 20μTesla, 200μTesla and 2000μTesla and can also measure in mGauss (200mGauss, 2000mGauss and 20000mGauss). with bandwidth of 30Hz to 300Hz.

To measure EMF the Extech 480826 uses a remote sensor attached via a cable to the main measurement unit. Measurements are shown on a built-in LCD screen in your chosen unit which can be switched between using a unit button on the front of the tester. A data hold function is also included to temporarily freeze the last value taken on the screen.


The 480826 Comes Supplied With:

  • Extech 480826 Triple Axis EMF Tester
  • Sensor with 3ft (930mm) Cable
  • 9V Battery
  • Hard Carrying Case

Key Features

  • Three axis (X, Y, Z) electromagnetic field measurements
  • Ideal for use around power lines, electrical appliances and industrial devices
  • Measures EMF in both μTesla and mGauss with three ranges for each
  • Wide bandwidth from 30Hz to 300Hz
  • Big digit LCD display makes viewing measurements easy
  • Data hold function temporarily stores last value taken on the screen
  • Remote probe attached to meter for ease of use
