Product Description

Portable Wheatstone Bridge - Physics Laboratory Equipment

• Portable Wheatstone Bridge designed to provide an accurate and sensitive instrument for measurement of resistance and location fault in cables by adopting the Murray or overlay loop circuit for tests
• Range : 0.01 ohms to 11.11 mega ohms.
• With constant coils , accuracy + 1%
• With Manganian coils , accuracy + 02%
• This Bridge is fully portable with a built in sensitive Galvanometer and a dry battery.

Series Arm: There are 4 decades of 10×1, 10×10, 10×100 and 10×1000 ohms

Range Multipliers: A single rotary switch furnishes 7 range multipliers of X1000, X100, X10, X1, X0.1, X0.01 and X0.001.

Battery: A built-in dry battery of 4.5 volts. There is a provision for using external battery for measuring high resistances.

Galvanometer: Galvanometer of Model MO 65 with sensitivity 10 microamperes/ div. is used.
