The difference between fluxmeter and Gauss meter and their advantages and disadvantages
As for fluxmeter and Gauss meter, many people can’t distinguish these two kinds of magnetic measuring instruments. They are commonly used measuring instruments by magnet manufacturers. What’s the difference between them? What are their advantages and disadvantages? Today, John is going to share with you.
What is a gauss meter?
Table of Contents
Gauss meter, also known as Tesla meter, uses Hall element theory to detect the magnetic induction intensity of a point and a surface on a magnetic material or object. The reading of Gauss meter is in Gauss or millisecond.

What is a fluxmeter?
Fluxmeter is a unit of Weber which uses the principle of electronic integration to detect the overall performance of magnetic materials or objects through coils. There are magnetoelectric, electronic and digital integration fluxmeters commonly used. General unit: Mwb, WB and other units.

Introduction to the advantages and disadvantages of fluxmeter and Gauss meter
Advantages of gauss meter: convenient, intuitive, easy to carry.
Disadvantages of gauss meter: point test, uncertainty, different people measure different, different manufacturers Gauss meter measurement value is not the same, the same Gauss meter probe different measurement value is not the same, test data has great divergence, the reason is the Gauss meter probe chip, probe packaging thickness, chip location, test Gauss value is difficult to be the same point test, chip size is different At the same time, the magnetic field of the magnet meter is not uniform. The factory standard of Gauss meter is calibrated in uniform magnetic field, so it is difficult to unify and compare the values measured by Gauss meter.
Advantages of fluxmeter: it is an ideal instrument for measuring magnetic field and flux. The measurement is the overall average value of the magnet, which can reflect the overall performance of the magnet. The value of the magnetic flux can be completely compared and transferred. The magnetic flux can reflect the overall performance of the magnet. For example, if the surface magnetic field is high (a certain point is high, which can not represent all), the magnetic flux is not necessarily large; on the contrary, if the magnetic flux is large, the magnetic flux performance must be good (the synthesis of all magnetic lines in the magnet).
Disadvantages of fluxmeter: coils of different sizes must be made for each magnet sample of different specifications. Strictly speaking, for very thin samples, the preparation of detection coils is difficult, laborious and inefficient.
Magnetic flux of magnetometer = field strength x area (under the condition of uniform magnetic field)
The magnetic field strength of Gauss meter is the field strength of “a certain point”.
