Turbidity Sensor VisoTurb®
With the VisoTurb® 700 IQ WTW presents a family of optical sensors for turbidity measurement. These sensors incorporate a ultrasound cleaning system that guarantees low maintenance and long-term reliability of the sensors. Turbidity measurements in aqueous media with VisoTurb® are carried out nephelometrically in compliance with EN ISO 7027.
VisoTurb® Turbidity Measurement according to the Nephelometric Principle
Using this principle, scattered light is measured at an angle of 90 degree. This method is ideal for low and medium range turbidity up to 4000 FNU. In compliance with EN 27027 and ISO 7027, infra red light with a wavelength of 860 nm is used. This wavelength is outside of the visible range – thus potential colouration of the sample does not effect the measurements.
