H W Sullivan

The H W Sullivan company was originally formed to manufacture submarine telegraphic instruments and test equipment, but is probably best known for the latter products. An interesting history of the H W Sullivan organisation is embedded below.

Sullivan measurement equipment has graced many standards laboratories around the world for decades.

The product range included many reference standards - including resistors, capacitors and inductors - as well as measuring instruments, such as Wheatstone bridges, inductive voltage dividers and indicating meters of various kinds. All were of excellent construction.

There are various Sullivan devices in the collection - please select an item from the sidebar for further details.
