Product Overview:
The urea online monitor uses spectrophotometry for detection. This instrument is mainly used for online monitoring of swimming pool water.
This analyzer can operate automatically and continuously without human intervention for a long time based on on-site settings, and is widely applicable for online automatic monitoring of urea indicators in swimming pools.
Product principle:
Urea reacts with diacetylone and antipyrine to produce a yellow color, and its absorbance is proportional to the content of urea.
