1041 Low Ohm Resistance Box Details
|
|
| Product Description |
Low Ohm Resistance Box
• 0.01Ω to 1kΩ
• 10mΩ resolution
• High stability and low temperature coefficient
• Ideal for Platinum Resistance Thermometer simulation
The 1041 is a compact, robust, and accurate
decade resistance box designed for applications in
both industry and education. With its low resistance
ranges the 1041 is particularly suitable for
simulation of platinum resistance thermometers.
Switch Contacts
Special attention has been given to the problem of
reliability of operation. A special multiple gold
contact arrangement ensures low contact
resistance and continued operation even if a
contact should fail.
Resistance Range: 0.01Ω to 1kΩ in 0.01Ω steps
