The manufacturer of YC40 Series Standard Magnets for Calibration tells you that the calibration standard is a reference magnet that the user can use to check the accuracy of the measuring probe that matches it. If the probe is functioning properly, the measured value specified on the corresponding calibration standard is achieved. If the deviation is out of tolerance, factory calibration of measuring instruments, probes and calibration standards is recommended.

The manufacturer of YC40 Series Standard Magnets for Calibration tells you that standard magnets can easily, quickly and stably verify and calibrate the accuracy and accuracy of Hall-effect Gaussmeters, Teslameters, and probes. Standard magnets are shielded to minimize the effects of external magnetic fields. Standard magnets act like weights on a balance, and the weights allow the balance to be calibrated. Standard magnets can be used to calibrate and verify the precision and accuracy of various Hall-effect Gaussmeters/Teslameters, etc.
YC40 Series Standard Magnets for Calibration is a permanent magnet specially designed for Hall film calibration. It is small in size and light in weight. It is suitable for calibrating Hall film with 0.1%~1% accuracy. The magnetic field level is 0.1T~1.1T stage optional. The highest magnetic field can reach 3.0T.
