摘　　要：介绍了一种以单片机作为控制系统的新型溶解氧测定仪的结构和其测量方法,此方法适合于各种类型膜电极.该仪器减少了传统溶氧仪器测量时,测量结果受温度影响的缺点,测定结果可精确至0.1mg/L.此外,本设计能随时由用户根据当时使用电极的温度特性输入至E2PROM2864中,可以长期获得正确补偿.This paper introduces structure and principle of a new dissolved oxygen meter with single chip microcomputer. Not only does this meter decrease the drawback of temperature effect which is present in the traditional DO instrument, it also fits for all kinds of cell electrodes. In addition, according to the current temperature character, consumers can obtain a long period of correct compensation and lay it in E 2PROM2864.
