Resistance Decade Box

Your Decade Box Source...

IET manufactures resistance, capacitance, and inductance decade boxes that cover a broad range of applications for the field, the laboratory or automated stations. Hundreds of models are available from the highest precision and performance to cost effective. If you don’t find the decade box you need from the standard models, we will build it for you.

IET Labs, maintains some of the finest R, L and C calibration standards in the World. IET Labs continues to manufacture and support a wide variety of products that were originally manufactured by GenRad, esi, QuadTech and others. The majority of IET’s products are manufactured with pride in the USA.
