一种胶体电荷测定装置的改进

摘要

介绍了目前应用广泛的胶体电荷测定仪,针对其测量样品池提出一种改进方式.该装置在基于流动电流测量原理的前提下,引进数字数据蓝牙传输和无线供电的新技术.通过改变微弱流动电流的处理方式与信号传输模式,使流动电流信号在测量过程中减少损失,从而保证胶体电荷测量更加准确和方便.%The colloid charge detector widely used nowadays was introduced.The paper suggested a method to improve the sampling chamber of the instrument.Based on the measurement principle of streaming current,the new technologies of data transmission with bluetooth and wireless power supply were brought in.Through the changes of weak current signal handling method and signal transmission mode,the losses of streaming current signals in measurement process could be reduced,it made the equipment more precise and convenient.
