To Indicate Residual
Magnetism
In Iron And Steel Objects
The Magnetic Analysis Magnetism Detector is widely used by steel
suppliers and fabricators to indicate the degree and polarity of residual
magnetism in ferrous products.
Easy to use, simply place the base of the indicating needle against the
object you are testing. The needle indicator will move to a point on the
scale that represents the strength of the magnetic field of the material
(in gauss). The meter scale reads 20 units on either side of a zero
center point, allowing for quick identification of the field’s polarity as
well as the level of the magnetic field.
Full scale deflection is equal to approximately twenty gauss. When
checking magnetized bar stock or tubing, a reading of 10 or less is
usually acceptable. Each piece should be tested separately, so that the
reading is not affected by adjacent parts.
The magnetism detector may be damaged if not handled with
reasonable care. It should not be dropped or subjected to severe
mechanical vibration or strong magnetic fields such as from high
horsepower motors, generators or welding equipment. For more
information on care, see instructions supplied with shipment.

Sensitivity & Calibration
Magnetism Detectors are calibrated prior to shipment, as signified by the sticker applied and initialed by
a member of MAC’s Quality Control staff. Calibration to a Level of +/- 1 gauss at 10 gauss is performed
utilizing a calibration fixture, calibrated with a gaussmeter which has been calibrated in accord with
standards traceable to the N.I.S.T.
For those applications where the sensitivity of the instrument, as supplied, is of high significance, the
full-scale reading (+/- 20) is obtained when the meter is subjected to a field whose known intensity is 20
gauss plus or minus 10%.
