Seaward Cropico 008-A [930168] Precision Grade 0.01 Decade Box

The Seaward 008-A Cropico High Accuracy 8 Decade Box, 111,112.11 Ohms is a versatile decade resistance box with 8 decades. High Accuracy and wide range 0.001 Ohm to 11 MOhms are combined in a compact lightweight case. The switches have gold plated contacts to ensure a low contact resistance and negligible thermal E.M.F. The 008A model can employ the Waidner Wolf technique to eliminate the errors switch contact resistance and is particularly suited to Pt100 simulation with resolution as low as 0.001 Ohm (> 0.0025 °C).
