Gauss meter 138A probe

138A Gauss Meter is exclusively used to test the flux density of all kinds of magnetic components. Regardless of what its material or the shape of the magnet is, Model-138A can test its flux density.

For example Ferrite Magnets、Flexible Rubber Magnets 、Rare Earth Magnets、Alnico Magnets…can all be tested by Model-138A. Also, Magnets for loudspeakers 、 headphones 、microphone magnets 、 motors, and relays, as well as other magnetism components can all use Model-138A to test their flux denstity.138A is specially designed with “Peak Hold” & “Auto Accumulating and Auto-Averaging” two functions, especially suitable to test the flux density of the magnetic gap of loudspeaker 、headphone and microphone…etc.
