摘要
浊度仪由传感器、放大器和显示器组成。传感器采用散射透射光度之比的测量方法和光电器件互补设计 ,浊度在 0～ 40 0NTU的范围内 ,直接输出线性信号 ,线性度可调。放大器的输入采用绝对测量电路来提高测量浊度的精确度和稳定度 ,使仪器受环境温度、测量光束或器件老化的变化影响很小 ,浊度读数准确、稳定、线性范围宽 ,适用于污水、饮用水、地表水处理、水的循环利用及化工、石油、选冶、印染、造纸、制药。
The turbidimeter is composed of a sensor, an amplif ier and a display. The sensor measures in the ratio between scatter and transmis sion and is designed by photoelectric complementarity. The turbidity ranges betw een 0～400 NTU. The sensor outputs directly linear signal. The linearity is adju s table. Input of the amplifier uses absolutely measuring circuit to increase the accuracy and stability of the measure of turbidity. The turbidimeter is influenc ed little by the changes of surrounding temperature, measuring light and aging o f apparatus. Turbidity reading of apparatus is accurate, steady and with broad l inear rang. It can be applied to measure the turbidity of waste water, drinking water, surface water, cyclic water and multi liquid from chemical industry, pet roleum, mill plant, printing, paper mill, pharmacy, food products etc.
