用于海水中实时测量的氨氮测量仪

Three-Electrod-Combined Probe Online Measurement of Ammonia-N Concentrations in Seawater

本文介绍一种新型的用于海水中实时测量的氨氮传感器。该传感器具有 NH3/p H/T三电极复合式探头 ,能实时地将海水的酸度 ,温度以及氨的含量快速准确地测量 ,并由 DSP(TMS32 0 F2 0 6 )为核心的数字信号处理系统对测量结果进行收集 ,分析处理 ,通过 RS2 32 /RS485将数据传送至陆地上的主系统。传感器处于自动运行模式。可在海水中连续一个月无故障工作 ,测量精度好于10 %

This paper presents a novel ammonia probe online measurement of Ammonia\|N concentrations in seawater which combined three electrodes of NH 3/pH/T. The ammonia meter with a DSP (TMS320F206) controlling system is used to automatically collect and process the data of NH 3,pH and Temperature T, and send them to the host on shore by means of RS232 port. Having continuously worked in seawater for a month, it runs pro perly and shows that the accuracy of measurement was better than 10%.
