摘　　要：本文介绍了一种能满足海洋调查要求的高精确度数字式温度记录仪。其量程为－３～＋３７℃，精确度为±０．０５℃，分辨率±０．０１℃。它以低功耗单片微计算机、液晶显示器和Ｖ／Ｆ变换接口为基础，采用干电池供电。仪器适于在室内、野外和海上多种用途的精密测温及自动记录；具有标准的并行打印接口和Ｒ５－２３２串行接口。这种仪器已在一些项目中实际应用。This paper describes a high accuracy temperature recorder, which can be used in oceano graphic measurements.The instrument,with a measuring range of-3 to+37℃,an accuracy of±0.05℃ and a resdution of ±0.01℃, is based on a low power single chip microcomputer,aV/F conversion interface and a LCD display.The instrument is battery powered,so that it is adaptive for accurate temperature measuring and recording for different purposes in labs, in the fields and on the sea. It has a standard parallel printer interface and a RS 232 serial interface.The instrumenthas been successfully used in several projects.
