Berg offers gages from Magnaflux including pie field gages and gauss field indicators. Our pie gages are useful for determining the direction of magnetic fields or for finding defects in ferrous metals and our analog field strength meters are both uncalibratable and calibratable while measuring the strength of a magnetic field or the magnetism of an object. If you have any questions about our analog field strength meters, please give us a call at 1-847-577-3980 or send an email to info@bergeng.com. Our knowledgeable staff is there to help and assist you.
