Reference Magnets

Reference Magnets provide a stable and convenient method to verify the accuracy and calibration of Hall Effect Gaussmeters, Teslameters, and Probes. Magnetic Instrumentation’s Reference Magnets are self-shielded to minimize the effects of external magnetic fields. For maximum accuracy, the gauss value of the Reference Magnet – and the field to be measured – should be on the same meter range and approximately the same value.

FEATURES

  • Precision Reference Devices for Hall Effect Probes and Meters
  • Self-Shielding Configuration
  • Many Standard Values Available
  • High Degree of Stability
  • Accuracy Retained Between 0°C and 40°C (32°F and 104°F)
  • Special Gauss or Tesla Values can be quoted on request
  • Both Axial and Transverse Reference Magnets are available
