High Accuracy DC Resistance Wheatstone Bridge Single Bridge DC Resistance Measurement(Wheatstone Bridge)

MEWOI OEM/ODM  Instruments Manufacturer

INTRODUCTION

Xtester-QJ23E portable Wheatstone bridge is equipped with a built in  galvanometer and batteries, designed for the measurement of resistance over  the range of 1 ohm to 1110000ohms, All parts are mounted in an aluminum case  And the instrument can be carried with ease.

All  the resistance elements are of well-aged manganin wire with low temperature coefficient  and non-inductively wound, sharing a high stability & accuracy.

The  type V switches used in the instrument enjoy a long operating life. The contact  elements are light stable, and good-repeatability.

MAIN FEATURES

1,  Xtester-QJ23E is a portable two terminal DC bridge. The control range is 0 ~  110m Ω, which is divided into seven ranges, and the accuracy is grade 01,It  is suitable for measuring various DC resistance in laboratory, workshop and  field without AC power supply

2,  The P Ⅲ high-strength plastic shell made of T300 polypropylene  resin which has the advantages of beautiful appearance, corrosion resistance  and corrosion resistance, Good extrusion performance, especially suitable for  field use

3,  The bridge adopts jz8 high-performance electronic amplification zero pointing  instrument, which is only set with mechanical zero adjustment without  electrical zero adjustment, and has the function of automatically cutting off  the power supply. The zero indicator has the characteristics of high  sensitivity, good reliability and strong overload resistance. It is as simple  to use as the tension wire galvanometer.

4,  The resistance element used in the bridge adopts low temperature coefficient  manganese copper wire, which is wound on the porcelain tube in a non  inductive way, and is subject to strict process treatment and long-term  manual experience, so the resistance element has high accuracy and good  stability
