产品概述

环氧树脂介电常数测试仪满足标准:GBT 1409-2006测量电气绝缘材料在工频、音频、高频(包括米波波长在内)下电容率和介质损耗因数的推荐方法

 

介质损耗和介电常数是各种电瓷、装置瓷、电容器等陶瓷,还有复合材料等的一项重要的物理性质,通过测定介质损耗角正切tanδ及介电常数(ε),可进一步了解影响介质损耗和介电常数的各种因素,为提高材料的性能提供依据;

仪器的基本原理是采用高频谐振法,并提供了,通用、多用途、多量程的阻抗测试。

 

环氧树脂介电常数测试仪以单片计算机作为仪器的控制,测量核心采用了频率数字锁定,标准频率测试点自动设定,谐振点自动搜索,Q值量程自动转换,数值显示等新技术,改进了调谐回路,使得调谐测试回路的残余电感减至zui低,并保留了原Q表中自动稳幅等技术,使得新仪器在使用时更为方便,测量值更为精确。

 

仪器能在较高的测试频率条件下,测量高频电感或谐振回路的Q值,电感器的电感量和分布电容量,电容器的电容量和损耗角正切值,电工材料的高频介质损耗,高频回路有效并联及串联电阻,传输线的特性阻抗等。
