- Analog Gauss Meter - Range +-20 Gauss - Option c/w Calibration Certificate is also available - Model DET-432 - 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. 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%.
