Product description
General
To keep good quality in industrial or drinking water and rivers or streams, “Turbidity” is one of the important measurement parameters to control water quality.
Turbidity analyzer is more than ever demanded not only for water treatment, but currently for measurement/detection of suspended substances in industrial waste or of turbidity at chemical processing facility.
Since their sales began in 1959, Yokogawa turbidimeters have been continuously developed and improved using various measurement principles suited for various applications. With its many achievements, Yokogawa has earned its customers’ confidence.
Right Angle Scattered Light Turbidity Analyzer, composed of Turbidity Detector TB820D and Liquid Analyzer FLXA402T, is a next-generation analyzer, developed based on years of experience, combining the reliable measurement principle with our latest digital sensor technology realizing high efficiency in facility operations.
FLXA402T is a converter designed, being tailored from the well-received FLXA402, to provide multiple detector measurement. In addition to conventional analog output, Modbus TCP, Modbus RTU/RS485 are available.
The technology of predictive maintenance prevents accidental shutdown of the factory and reduces OPEX. TB820D has drastically improved maintainability and minimized the maintenance time.
