The Time Electronics 1051 is a precision low ohm resistance box designed for general laboratory work including platinum resistance thermometry. Compact and durable, it is housed in a robust metal case with a removable protective rubber cover, making it ideal for both laboratory and field use.

High stability metal film resistors achieve excellent accuracy of up to ±0.1%. An 8-digit thumbwheel switch enables simple and precise setting with clear indication of the resistance value. The 1051 offers small increment steps of 0.01Ω over a range of 0.01Ω to 1MΩ.

Special attention has been given to operational reliability. A multiple gold contact arrangement ensures low contact resistance and continued operation even if a contact fails. Color-coded digits (red for kilohms, white for ohms, yellow for milliohms) make selecting and reading settings easy. Safety terminals are compatible with 4mm shrouded plugs, standard plugs, bare wires, and spade terminals.
