Digital handheld Gaussmeter for the measurement of magnetic field strength.
The F.W. Bell 5200 Series Gaussmeters replace the highly successful 5100 series.
Permanently magnetized steel disc containing coarse and fine cracks. Used to test the performance of the magnetic particle materials and lighting environment.
A set of two panels, each measuring 3.875 x 1.875 inches (100 x 35mm), sheared from the same stock with matching crack patterns. Makes simultaneous comparison of two penetrant batches practical. Specify crack sizes of 10µm, 20µm, 30µm, 50µm.
