Overview

Overview

The WTW IQ Sensor Net VisoTurb® 700 IQ Turbidity Sensor is 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.

Product Features
  • Optical based turbidity/TSS (Total Suspended Solids) sensor for the IQ Sensor Net control system.
  • Ultrasonic cleaning
  • Extremely low-maintenance
  • Highly accurate factory calibration
  • High operational safety (sensor check function)
  • 2-year Warranty

WTW 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.
