Product Description

Huazheng Electric QJ57E Portable High Accuracy Kelvin Double Bridge for Low Resistance Measurement

Product Description

 

1 1 Uses: Model QJ57E is a portable accuracy DC double bridge with Kelvin network ( hereinafter referred to as "Bridge"). The instrument is provided with seven measuring ranges from 0 ~ 1.1111k Ω and the minimum resolution is 0.01 u Ω . It is suitable for accuracy measurement of low-value resistance or DC resistance in the conductivity of metal conductor, DC current divider, the contact resistance of switch, wire and cable, motors and transformers, etc.

1. Features: The main resistance element of the bridge is made by high-grade alloy material, and subjected to long-term high and low temperature aging test, as well as rigid technological treatment and adjustment so as to lower the temperature coefficient, increase the accuracy and improve the annual stability. By adopting the specific switch in Fang Ke accuracy instrument, the contact resistance of the bridge is small and so does its variation; by using model JZ2B zero indicator, the bridge features high sensitivity, low noise and less power dissipation. Therefore, the portable bridge is characterized by wide measurement range, high accuracy, well stability and reliability, compact and lightweight
2. Specifications

1. All technical indicators of Model QJ57E conform to the standard IEC564 - 77" DC Bridge for Measuring Resistance".
2. Environment condition

1. Temperature:

Reference value: 20+0.5 C , nominal value" 5 °C-25 °C .

1. Relative humidity:

Reference value: 40%-60%, nominal value: 25% ~ 75%.

1. Main parameters are shown in Table 1.
