QJ31E Wheatstone Kelvin Resistance Bridge.
The Type QJ31E Portable Wheatstone / Kelvin
Resistant Bridge is designed for the high
measurement of low resistance, conductivity and calibration of other
It is totally self-contained so is suitable for laboratory, workshop and onsite, in the field, applications.
The Portable Wheatstone / Kelvin Bridge has a resistance range from 0.0001ohm to 100ohm for the Kelvin bridge and 10ohm to 1Mohm for the Wheatstone bridge. The basic accuracy is ± 0.1%.
