The TB750G turbidity analyzer uses a right angle light scattering method that provides highly reliable measurements and improved maintainability. It is best suited to find the turbidity of finished water and water used in general processes. A wide range of options are available to meet users’ needs.


  • Highly reliable measurement with excellent linearity and repeatability.
  • Easy-to-clean cell.
  • Compact, lightweight converter and detector.
  • User configurable measuring range: 0-0.2 NTU to 0-100 NTU.
  • Measuring range switching (2 or 3 ranges).
  • Enhanced self-diagnostic function as standard.
  • Detector structure to remove sudden reading change caused by bubbles.
  • A wide range of measurement conditions.
  • 2 analog outputs, 3 relay contact outputs, and 1 serial communication.
