Brand：Erun
Name：Online water transparency monitor
Model：ERUN-SZ4-A-A8C
Parameter：Transparency (transmittance)
ERUN-SZ4-A-A8C water transparency online detector sensor adopts the principle of transmission measurement, customized optics, compact size, easy to install and maintain, no reagents, no pollution, more economical and environmentally friendly. With 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 also maintain excellent stability. Widely used in surface water, tap water, sewage, aquaculture industry and other water quality transparency for continuous real-time monitoring.
