Cropico 00 Series
The Cropico 00 Series (005 / 006 / 008) is a versatile range of high-accuracy resistance decade boxes, available in 5, 6, and 8 decade configurations. They combine a wide resistance range from 0.001 Ω to 11 MΩ in a compact, lightweight case.
Gold-plated switch contacts ensure low contact resistance and negligible thermal EMF. Selected models employ the Waidner-Wolf technique to eliminate switch resistance errors, making them ideal for Pt100 simulation with resolutions as fine as 0.001 Ω (0.0025 °C).
