标准电阻

标准电阻器（standard resistor） 用于保存电磁单位制中电阻单位欧姆的量值的标量具。 是专为精密仪器或校准电阻值而设计的。技术上与精密线绕电阻器的要求大体相同，并要求阻值稳定性极高，必须是无感和分布电容极小。主要具有高精密，低温度系数的特点。但应指出，它们的阻值往往是以某一温度和湿度为前提而标出的。 标准电阻是电阻基本单位Ω（欧姆）的度量器，产品具有电阻精度高、温度系数低、稳定好的特点，在精密测量和计量检定部门作传递用。山西省计量科学研究院可开展标准电阻的检测，提供的数据准确可靠。

A standard resistor is a measuring standard that preserves the magnitude of the ohm (Ω), the resistance unit in the electromagnetic unit system. It is specially designed for precision instruments or resistance calibration. Technically, its requirements are generally consistent with those of precision wire-wound resistors, and it must feature extremely high resistance stability, be non-inductive, and have minimal distributed capacitance. Its main characteristics include high precision and low temperature coefficient. It should be noted that their rated resistance values are usually specified based on a given temperature and humidity condition. A standard resistor serves as a measuring standard for the basic resistance unit Ω (ohm). The products feature high resistance accuracy, low temperature coefficient and good stability, and are used for quantity value transfer in precision measurement and metrology verification institutions. The Shanxi Institute of Metrology Science is capable of conducting standard resistor testing and providing accurate and reliable test data.
