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 and conductive meters.
- Fully customisable 1-dial resistance box (up to 24 resistance values)
- Up to 5-digit resistance values on switching contacts may be specified
- Resistance values available from 1Ω up to 1MΩ
- Improved work efficiency and elimination of careless mistakes
- Lightweight, compact size
- High precision
- High stability
The resistance elements utilise Bulk Metal® Foil technology and the connections to the rotary switch are made by using 4-terminal junctions. This ensures that high precision, high stability and low temperature coefficients are achieved.
The ADR-1xxx 1-Dial resistance box is fully customisable. Up to 24 different resistance values can be set into the box.
The ADR-1xxx series has a weight of approximately 1kg and dimensions of 100mm x 150mm x 80mm.
