Offering analog, Modbus, and SDI-12 communications
Overview
The ClariVue™20 is an ISO 7027-compliant, submersible, 90-degree, side-scatter turbidity sensor in a rugged titanium housing, making it the ideal choice for highly corrosive environments. The side-scatter turbidity measurement can be used as a surrogate for suspended sediment concentration (SSC) in aquatic ecosystems. The sensor returns data via SDI-12, analog, or Modbus to a data logger or controller for easy integration into your new or existing system.

Technical Description
The ClariVue 20 is designed to operate in fresh and saline environments. The sensor face is made from titanium to slow biological growth over the optical windows; however, the sensor requires regular maintenance to keep the optical window clean in high bio-fouling environments.
Caution: The ClariVue 20 may become damaged if it is encased in frozen liquid.
