摘要
针对目前国内接触式在线酸、碱浓度计寿命低、误差大及电极易污染的缺点,提出一种非接触式在线酸、碱浓度计的测量原理及实验电路,并给出了电路主要参数及实验数据。
Aiming at the drawbacks of the touched online thick degree meter of acid and alkali, such as the short life and the large error and the easily polluted electrodes, this paper presents the principle of measurement and the experimental circuitry for an untouched online thick degree meter of acid and alkali, and gives the main parameters of the circuit and the experimental data.
