QJ84A NumberDC double arm bridgeDetailed Introduction

QJ84A NumberDC double arm bridgeThe basic parameters are the same as QJ84. Powered by batteries and suitable for on-site use without AC power supply. It is an upgraded product of our factory's Kelvin bridge, which is based on bridge circuits and uses precision alloy wound resistors as the benchmark. QJ84A NumberDC double arm bridgeNot only does it have the same simple, fast, and eye-catching features as a digital multimeter. At the same time, it inherits the advantages of accurate, stable, and reliable Kelvin (double arm bridge) bridge. It is an ideal product for precision measurement of various types of DC low value resistors by industrial and mining enterprises, scientific research units, colleges and universities, and metrology departments.

Accuracy is superior to that achieved by an external galvanometer connected to a DC resistance bridge of the same level.

Simply connect the tested resistor and select the appropriate range, without the need for manual operation during the testing process.

The fast sampling time is 0.4 seconds, and stable data can generally be displayed within a few seconds.

Featuring a 200mm large digital display, the handwriting is clear and easy to read.

The stable main reference resistor is made of precision manganese copper alloy wire winding. Stability is better than 0.02%.

The reliable main components are imported original and specially selected for aging.
