Overview

The fluorescence dissolved organic matter analyzer can be directly connected to the CDOM analyzer through a digital communication interface to provide simple, reliable, and cost-effective on-site sensor monitoring data. The organic matter detection meter in water also has remote status display, calibration, setting, and fault diagnosis functions. IP68 rated dust-proof and waterproof sturdy shell, 1500N high-strength Kevlar cable, with a maximum transmission distance of over 1.2 kilometers. The colored soluble analyzer is directly installed in water quality analyzers for applications such as reservoirs, rivers, tap water, and sewage.
