YC40 Series Standard Magnets for Calibration is made of high-performance permanent magnet materials. These high-quality standard magnet products have long-term stability. The standard magnets can be used stably between 0-70°C, and the temperature coefficient is -0.03%/°C , because the temperature coefficient is negative, so when the temperature rises, the magnetic field strength decreases.

YC40 Series Standard Magnets for Calibration can easily, quickly and stably verify and calibrate the precision and accuracy of Hall-effect Gaussmeters, Teslameters and probes. Standard magnets are self-shielded to minimize the effects of external magnetic fields.
The function of YC40 Series Standard Magnets for Calibration is similar to the weight on the balance, and the weight can calibrate the balance. Standard magnets can be used to calibrate and verify the precision and accuracy of various Hall-effect Gaussmeters/Teslameters, etc.
