摘要
介绍了溶解氧分析仪的硬件结构和软件设计。该仪器由极谱型复膜氧电极传感器和ＡＴ８９Ｃ５２单片微机系统两大部分组成，软件采用模块式编制，结构紧凑，操作简便。仪器的测量范围为：溶解氧：０～１９．９９ｍｇ／Ｌ（温度为－１０℃～４０℃）；测量精度：溶解氧±０．
he hardware structure and software design of an intelligent analyzer for dissolved oxygen are introduced. This analyzer consists of two parts:AT89C52 singlechip microcomputer system and polarographic type, filmcoated oxygen pole sensor. The software is of modular programming. The analyzer features with compact structure and easy operation. The measuring range of the instrument is :dissolved oxygen: 019.99mg/L(at temperature of-10 deg C_40 deg C);measuring accuracy:dissolved oxygen+/-0.3mg/L(at temperature of+/-1 deg C).
