摘要
化学需氧量(COD)是衡量水体污染的一个综合性指标,COD检测仪由三电极氧传感器、处理器、温度补偿、气压补偿等电路组成,其中三电极氧传感器克服了被测溶液的干扰,满足测试过程中电解电流稳定的要求。海水COD检测仪设计的最终目标是在此三电极COD检测的基础上,基于GPRS数据传输网络,实现此系统的定时测量、无线传输、直观显示、自动报警、动态监测、支持短消息服务等功能。
Chemical oxygen demand（COD）is a comprehensive indicator to measure water pollution, COD detector is composed by three electrodes oxygen sensor, CPU,temperature compensation, pressure compensation circuit etc, three electrodes oxygen sensor has overcome the interference of measured solution, and meet the demand to keep the electrolysis current stable in the testing process. Through the date transmission network--GPRS,the COD seawater determination,on the three electrode COD monitoring, is designed to achieve the following functions：timing measurement, wireless transmission, visual display, automatic alarm, dynamic monitoring and supporting short message service, etc.
