Magnetic field, electric field and radio frequency strength can all be measured at the same time with Extech's multiple-field EMF meter, the EMF450.
Made for use testing home appliances, power lines, electrical appliances, industrial devices, mobile/cell phones and base stations, the EMF450 includes a magnetic field triple axis sensor (X, Y and Z) and a high quality, full colour-screen which can show readings as digital values, bargraphs or trending graphs.
Need to make comparisons? The EMF450 has the ability to store up to 20 historical records for this purpose. It also comes with a data hold function for temporarily storing the current value on the screen and an automatic power off function to help conserve battery life.
