QJ83A digital DC single arm bridge (portable)

QJ83A digital DC single arm bridge (portable)The basic parameters are the same as QJ83. Powered by batteries and suitable for on-site use. It is a digital bridge in our factory that is truly based on bridge circuits and uses precision alloy wound resistors as the benchmark. It is an updated product of Wheatstone bridge. It has the characteristics of being as simple, fast, and eye-catching as a digital multimeter, while maintaining the accuracy, stability, and reliability of the Wheatstone bridge. Easy for users to use, no need for zero adjustment, no need for standards, and fast testing, it is the best choice for precision measurement of various DC resistors in industrial and mining enterprises, scientific research units, and metrology departments.

Product Features:

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.

Eye catchingQJ83A digital DC single arm bridge (portable)Adopting 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.
