Brand：Erun
Online sludge concentration water quality monitor
Model：ERUN-SZ2-B-A6
Sludge concentration (infrared scattering method)
The sludge concentration sensor adopts near-infrared LED light source and WinRun's unique adaptive software algorithm, which can effectively remove the interference of external light. The sensor does not require reagents, no pollution, more economical and environmentally friendly; equipped with an automatic cleaning brush can eliminate air bubbles, reduce the impact of contamination on the measurement, so that the maintenance cycle is longer, long-term online use can maintain excellent stability. Widely used in surface water, municipal sewage, industrial wastewater, sewage treatment, industrial processes and aquaculture water sludge concentration for continuous real-time monitoring.
