GAUSS METER PROBE 138A

GAUSS METER Probe 138A

138A Gauss Meter is exclusively used to test the flux density of all kinds of magnetic components. Regardless what its material or the shape of 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 loudspeaker、headphone、microphone magnet、motor and relay, as well as other magnetism components can all use Model-138A to test its flux denstity.138A is especially 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.

A pen-like bar. Before using, the user must pull back the upper half portion of
the probe’s protector, to emerge the sensor chip for testing, right after the
testing, the user must pull back the probe’s protector to its original position, to
prevent damage to the sensor chip.
NOTE ：User must hold gently the upper both sides of the probe’s protector, then, gently
pull backward the probe’s protector, never press the tip end of the probe’s
protector to press backward the upper half portion of the probe’s protector,
since this will damage and break the sensor chip. Please refer to the following
figures.
