Magnaflux Field Indicator helps to indicate residual magnetism after magnetic particle testing. This field indicator is non-certified, inexpensive and disposable. Offers complete flexibility in measuring residual part magnetism, field direction and AC/DC field strength in MPI equipment applications. This indicator quickly reads the amount of residual magnetism left in a part when the indicator arrow is placed against a magnetized part. The field indicator is available in general-purpose, non-calibrated and calibrated models.
