Product Description A Digital DC Double-Arm Electric Resistance Tester is a device used to measure the electrical resistance of various materials, including metals, alloys, and other conductive materials. It works by passing a known amount of electrical current through a sample and measuring the voltage drop across it, which is then used to calculate the resistance of the sample.The double-arm feature allows for the measurement of the resistance of longer samples, as it can apply the necessary force evenly across the entire length of the sample. The digital display allows for accurate and precise readings, making it an essential tool in many industries such as electrical engineering, metallurgy, and manufacturing.Product Description:QJ84 digital DC bridge is the Kelvin bridge replacement product, suitable for industrial and mining enterprises, laboratories, or workshops on-site DC low-value resistance for precision measurement.Function and characteristics: A. With 9/2 LED large number of readings, intuitive readings, clear, high precision measurement, good stability test speed. B. Measuring range: 0 ~ 20kΩ, divided into seven ranges, the minimum resolution of 1μΩ. C. The main resistance components using mature Manganese copper wire wire wound resistance, the temperature coefficient of small accuracy. D. Bridge with standard resistance, no external standard, you can calibrate the accuracy of the instrument. E. The use of thin plastic case, small size, light weight, handsome in appearance, easy to carry.
