세부내용 (Description) :
Very high accuracy resistance decade boxes with versatile wide ohm range
-. High accuracy 0.01% and high performance
-. Suitable for Pt100 and tranducer simulation
-. 5, 6 8 and 10 Decades
-. Long term stability ± 20ppm/year
A versatile range of Series decade resistance boxes available in 5, 6 8 & 10 decades.
High Accuracy and wide ranging from 0.001 ohm to 11 Mega ohm, in a compact lightweight metal case.
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 the errors switch contact resistance and are particularly suited to Pt100 simulation with resolution as low as 0.001 ohm (» 0.0025°C).
