1041 Resistance Decade Box

Description

A precision low ohm resistance box designed for general laboratory work

including platinum resistance thermometry. The 1041 is compact and durable,

housed in a robust metal case with removable protective rubber cover, making it

ideal for use in either the laboratory or field. Excellent accuracy is achieved by

using high stability metal film resistors. The 5-digit thumbwheel switch enables

simple and precise setting with a clear indication of the resistance value.

Switch Contacts: Special attention has been given to the reliability of operation.

A special multiple gold contact arrangement ensures low contact resistance and

continued operation even if a contact fails.

Clear Visual Indication: To make selecting and reading the setting easy the 1041

incorporates colour coded digits: ohms - white, milliohms - yellow.

Safety Terminals: Compatible with 4 mm shrouded plugs, as well as standard

plugs, bare wires, and spade terminals.

Added Protection: The 1041 comes fitted with an ergonomic rubber cover

providing increased protection and durability. It has a textured grip for comfortable

handling and side openings to place labels. It is easy to remove if the user prefers

a stand-alone unit or to house the 1041 in the optional 9026 carry case.
