Code
BU013
These Isochron springs are made to the original design but are made from Stainless steel instead of Invar or C902. They are a cheaper and more robust alternative. They are exactly the same size as BU004., but will not perform the temperature compensating to the same high degree.
Each is supplied in a clear perspex box.
Material is 0.15mm Stainless Steel, 18 coils of 4mm, 2 half end coils at right angles
Please read the Isochron story for further information.
