Measuring Coils for Connection to Electronic Fluxmeter EF 5

A variety of measuring coils for different applications is available from stock: field coils (search coils, point coils), moment coils (Helmholtz coils), potential coils, saturation coils and more. For details on our standard coil program please consult our coil data sheet. If you can provide details on your application we will be happy to assist you in choosing the right coil. Of course you can also connect self-made coils to the EF 5 or we can design special coils for you. Many sample applications and useful hints can be found in our booklet »Magnetic Measuring Techniques« by Dr. E. Steingroever and Dr. G. Ross, which can be obtained from us free of charge.
