QJ84A-digital and wide-range DC bridge is my factory original based on bridge circuit, and winding resistance precision alloys as a benchmark in the Kelvin bridge replacement products. Not only do they have a digital multimeter as simple, quick and smart features. While inheriting the Kelvin (double bridge) bridge accuracy, stability and reliability advantages. Is the industrial and mining enterprises, research institutes, universities, and measuring sector for various DC low resistance ideal products for precision measurements.
Accurate DC resistance bridge add-galvanometer is superior to the same level in order to achieve accuracy.
Simple connected was selected by measuring resistance range, the testing process no longer by hand.
Fast sampling time of 0.4 seconds, generally stable data can be displayed in seconds.
Smart 200mm digital, legible at a glance.
Precision manganin alloy wire is mainly used in the baseline resistance around the system. The stability is better than 0.02%.
Reliable major components imported original, aging and special matching.
