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 0.001 ohm to 11 Megohms 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 0.001 ohm (0.0025°C). High Accuracy Resistance Decade Boxes / 5, 6 & 8 Decades
