The TTurb is a digital sensor for optical turbidity measurements according to the 90° IR scattered light method. Depending on the sensor it can be used in pure water up to 100 FNU as well as in raw-, waste- and process waters up to 1000 FNU. TTurb is available with a 10 m or a 2 m fixed cable.

  • Reliable concentration measurements by optical methods
  • Pulsed infrared scattered light procedure
  • No mechanically moving parts
  • Digital reading
  • Preprocessing in the sensor increases measurement sensitivity
  • Measurement of turbidity in drinking water, domestic water, circulating water
  • Measurement of turbidity in drinking water treatment plants with low turbidity values
