Alpha ADR 1-Dial Series

The ADR 1-dial resistance box series from Alpha Electronics offers a range of standard resistors which are ideally suited for repetitive daily work. The single dial system means the resistance is easily switched from one value to another. This greatly improves work efficiency and helps to avoid mistakes, which may happen when using a 6-dial decade standard resistor. They are ideally suited for RTD simulation for platinum (Pt) related products a..
