| Abstract: | 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%. |
