Cropico 00 Series

005/6/8 High Accuracy Resistance Decade Boxes / 5, 6 & 8 Decades + Special Models for Pt100 Simulation.

A versatile range of resistance decade boxes available in 5, 6 & 8 decades. High Accuracy and wide range 0.001ohm to 11Megohms are combined in a compact lightweight case. The switches have gold plated contacts to ensure a low contact resistance and negligible thermal emf. Some resistance decade box models are particularly suited to Pt100 simulation with resolution as low as 0.001ohm (0.0025°C). High Accuracy Resistance Decade Boxes / 5, 6 & 8 Decades.

The switches have gold plated contacts to ensure a low contact resistance and negligible thermal E.M.F.

Some models employ the Waidner Wolf technique to eliminate any errors due to switch contact resistance and are particularly suited to Pt100 simulation with resolution as low as 0.001Ω (»0.0025°C).
