Abstract: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．
