TOTAL NITROGEN (TN) analyzer
WATER / LIQUID ANALYZER
Analyzed parameter: TN (NH4+, NO2-, NO3-)
Method: Liquid (NO2-, NO3-) and Gas-Phase (NH4+) UV FTLS Spectroscopy or full Gas-Phase UV FTLS Spectroscopy
Provides highly precise and selective quantification of Total Nitrogen using a patented measurement method. The system delivers rapid, interference-free readings with low maintenance requirements, ensuring reliable real-time monitoring and consistent performance in demanding industrial or environmental applications.
