研究设计了一种用AppleⅡ微机同时采集和处理四台721型分光光度计测试数据的装置。这种装置具有多种功能,可以直接打印出工作曲线和分析结果;吸光度测量精度及准确测定的吸光度量程均优于原721型分光光度计的表头读取吸光度的方式。
Research and design a device that collects and processes the data of four 721 spectrophotometers simultaneously with the Apple II microcomputer. This device has a variety of functions, you can directly print out the working curve and analysis results; absorbance measurement accuracy and accurate determination of the absorbance range are better than the original 721 spectrophotometer head read absorbance way.
