138A probe

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

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.
