RDB-10: Resistance Decade Box
$ 239.95 CAD
The RDB-10 is a handheld resistance decade box that creates a specific resistance value using a combination of switches. It offers 7 decades of resistance ranges, from 1 Ω to over 11 MΩ in 1 Ω steps. Easy-to-use slide switches allow for straightforward addition and subtraction of resistance values. The RDB-10 is a passive device that requires no power source. Housed in a rugged enclosure with an impact resistant rubber boot, the RDB-10 is a compact, convenient tool for engineering design and testing as well as calibration of test equipment.
