IQ SensorNet VisoTurb® Sensors

YSI IQ SensorNet UVVIS Ultrasonic Cleaning with UltraClean Technology

The ultrasonic cleaning of the UVVIS IQ SensorNet sensors. This short video demonstrates the ultrasonic cleaning when power is added to this sensor and the milky substance is quickly cleaned off. The UltraClean technology is continuously on and built into the sensor to prevent fouling.

Optical Turbidity and TSS Sensor for IQ SensorNet systems

  • Overview

    The VisoTurb® is an optical based turbidity or TSS (total suspended solids) sensor for the IQ SensorNet process monitoring and control system.

    • The VisoTurb sensors are precisely calibrated with a multi-point factory calibration. The calibration is extremely stable and there is no need to calibrate on-site. A matrix adjustment is possible as needed.  
    • UltraClean™ Ultrasonic Cleaning The ultrasound source is integrated in the sensor and generates high-frequency vibrations of the optical windows. Ultrasonic cleaning prevents biofouling resulting in maintenance free operation with accurate measurements every time. 
    • Measurement Principle Utilizes nephelometric measurement technology in accordance with EN ISO 7027 (DIN EN 27027 or ISO 7027). Sample discoloration does not affect measurements.
    • 2-year Warranty

    The sensor is part of our IQ SensorNet family of products and works directly with our advanced wastewater process monitoring and control platform the IQ SensorNet 2020 3G controller or our simplified IQ SensorNet 282/284 controller.
