The sun 138A Gauss meter
Sunshine 138A Gauss meter is used to test the magnetic flux density of the magnetic elements of various special equipment, no matter what the material and shape of the magnet 138A gauss meter can be used to test the strength of its magnetic field
Function IntroductionTechnical ParametersConfiguration Checklist
General test method / peak test method

Peak hold function, can be easily measured peak

Adding automatic and automatic average

The magnetic flux density of the magnetic gap between the magnet test speakers, the four-point test automatically mean adding, accurate, and efficient

Main purpose: a peak of accessing and automatic accumulation, automatic averaging function, suitable for use in speaker magnets, headphone magnets, microphone magnets magnetic gap flux density measurements.

Technical parameters
Digital display Digital table, resolution: 1 gauss.
Range of measurement 0~20K gauss,Automatic range two range: 0~2.0K, 2.0K~20.0K gauss.
