Time Electronics
1051 Resistance Decade Box
• 0.01Ω to 1MΩ
• High accuracy
• Clear visual indication
• High stability
• Low temperature coefficient
• Safety terminals
• Removable protective cover
• Suitable for PRT/RTD
DESCRIPTION
A precision low ohm resistance box designed for general laboratory work including platinum resistance thermometry.
The 1051 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 eld. Excellent accuracy is achieved by using high stability metal lm resistors.
The 8-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 1051 incorporates colour coded digits:
kilohms - red, ohms - white, milliohms - yellow.
Safety Terminals: Compatible with 4mm shrouded plugs, as well as standard plugs, bare wires, and spade terminals.
Added Protection: The 1051 comes tted 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 1051 in the optional 9026 carry case.
