QJ57E Resistance Kelvin Bridge.
The QJ57E Resistance Kelvin Bridge is a self-contained portable DC Kelvin Bridge for high precision
measurements of low resistance, conductivity and calibration of other instruments.
It is totally self-contained so is suitable for laboratory, workshop and onsite, in the field, applications.
The Portable Kelvin Bridge has a resistance range from 0.01μΩ to 1111.1Ω in seven ranges and an
accuracy of ±
0.03%.
