OWS-SCMW-MPx Multi-parameter Optical Water Quality Sensor

Category Tags , , ,
  • OWS-SCMW-MPx sensors can measure turbidity, chromaticity, COD, and TOC at the same time.
  • The turbidity measurement is based on the 90°scattered light principle, and the COD and TOC measurements are based on the ultraviolet spectrum absorption principle.
  • It adopts high parallelism and has an automatic light intensity correction laser light source and high sensitivity detector. The sensor is equipped with an automatic optical window cleaning function, long-term maintenance-free, and suitable for tap water application scenarios.
  • In addition, with the TRM series data transmitter and Ulik-Server  Cloud Service, users can realize on-site and remote data viewing.
