NL SERIES
Parameter: Nitrate
OVERVIEW
NITRATE SENSOR
Real Tech’s bypass Nitrate sensor provides real-time measurement of nitrate (NO3) in water or wastewater. Real Tech’s Nitrate sensors utilize UV-VIS light for measurement. Designed to meet the needs of many monitoring applications, the NL series offers multiple flow cell designs and sensor path length selections for the desired measurement range.
LIQUID AI® COMPATIBLE
Our Liquid Ai® data services complement our real-time water quality monitoring systems. Our Remote Monitoring platform is a powerful data management and visualization tool that enables access to data anywhere, anytime.
