Welwyn Electric, based in Northumberland, used to manufacture a wide range of precision resistors, some of which were offered as reference standards. They also used to maintain an excellent standards laboratory to support this range of products.
In more recent times, they have focussed more on microelectronic assemblies but some resistor products are still manufactured.
In this section you will find some of the fine resistance standards that have been manufactured by Welwyn Electric. Please select an item from the sidebar for further details.
