Yosemite Y550 series UV254 probe features highly reliable UV-LED light source. The proven technology is to provide reliable and accurate analysis of water and waste water with low maintenance. With compact design, and integrated turbidity sensor for turbidity compensation, it is an excellent solution for source water, municipal water and wastewater monitoring.
Operation Principle
UV254 probe provides in-situ continuous organics monitoring utilizing a 254nm ultraviolet LED source. The amount of light absorbed provides an indication of natural organic matter. It serves as a continuous surrogate measurement for organic carbon (TOC), COD, and SAC. The UV254 probe comes with built in turbidity compensation and LED reference to ensure accurate, stable, and reliable measurements.
