基于单片机的全自动定氮仪

The Nitrogen Determining Instrument Based on Mpu

为克服凯氏定氮分析方法中间步骤多 ,操作复杂 ,容易产生人为误差的缺点。介绍一种基于单片机的全自动定氮仪 ,并阐述它的工作原理、软硬件设计。该系统使工业定氮系统实现了高精度。

Nitrogen determining instrument is developed from the principle of Kieldahl's measurement that gauges the nitrogen content in organism. The paper presents this instrument, including the operating principle, the design of software and hardware. The instrument consists of MPU circuit and intelligent parts. This system is convenient in installation and debugging and full of useful functions that are leading domestically.
