摘要:
A device for the coulometric measurement of the thickness of thin metal layers of different material on a base has switch-over devices permitting switching to the measurement problem at hand and an electrolytic switch-over device. Accessible from the outside of the device, a first plug section, coupling electrical lines, is provided. Second plug sections having a shape necessarily resulting in correct plugging can be selectively plugged into the first plug section. The second plug section mounts electrical circuit elements of values pertaining to a separate measurement problem, which elements are connected to the plug contacts.
