IDS turbidity sensors with universal plug head – digital & wireless ready

WTW sensors digital IDS turbidity sensor VisoTurb® 900-P

Digital IDS turbidity measurement with a practical turbidity sensor for mobile applications in surface waters and process - the VisoTurb® 900-P



  • Convenient turbidity sensor for MultiLine® IDS for measurements on site
  • Simple 2 or 3 point calibration
  • Suitable for multi-parameter measurements

The new VisoTurb® 900-P is a turbidity sensor that works with IR for mobile applications, where the turbidity value is to be determined directly in the sample. It is robust and reliable with an exclusive, corrosion-resistant titantium housing, waterproof up to 10 bar. Its field of use is the measurement in surface waters, during pump tests, inspection of online measurements as well as in in-situ measurements in different applications. It works with all MultiLine® IDS portable meters and can be connected to AS/IDS-x cables of lengths of up to 100 m thanks to its universal plug head. Additionally it can be used in laboratory applications with inoLab® Multi 9310 IDS, 9620 IDS und 9630 IDS. The use with IDS wireless modules is recommended.
