Experimentations with Kelvin's Bridge Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12084
Indian Lab Suppliers supplies the Experimentations with Kelvin's Bridge (Product ID: 12084) as part of its electronics engineering lab equipment range. It is a Kelvin double bridge board for measuring very low resistances by the null method.
Quick Answer
The Kelvin double bridge is a refinement of the Wheatstone bridge that removes the effect of lead and contact resistance, so resistances well below 1 Ω can be measured. The board has three unknown resistances (0.5, 1.0 and 1.5 Ω), selectable known arms R1 (100 kΩ, 20 kΩ, 10 kΩ) and R3 (1 kΩ, 200 Ω, 100 Ω), a +5 V DC supply and a digital galvanometer for finding the null point. It runs on 230 V ±10%, 50 Hz mains and comes with five 2 mm patch cords and operating instructions.

Frequently Asked Questions
Why use a Kelvin bridge instead of a Wheatstone bridge?
It cancels lead and contact resistance, which matters when measuring resistances below about 1 Ω.
How is balance detected?
With the built-in digital galvanometer.
Which unknown resistances are supplied?
0.5, 1.0 and 1.5 Ω.
