Turb 750 T Benchtop Turbidimeter

Simplify turbidity measurements without compromising data quality

YSI’s Turb® 750 T benchtop turbidity meter provides accurate and precise measurements up to 1100 FNU/NTU at an affordable price. The turbidity meter complies with EPA 180.1 and includes analytical quality assurance (AQA), which allows for adjustable calibration intervals, calibration record of turbidity standards used, and GLP-compliant documentation via PC and LIMS.


With advanced features like intelligent reproducibility and plausibility check (IRPC), this powerful benchtop turbidity instrument can quickly take multiple measurements, automatically evaluate the data and remove outliers, offering your laboratory optimal efficiency.

These features and the affordability make the Turb® 750 T a great turbidity meter for environmental, chemical, petroleum, food, and beverage laboratories!

  • One of the most affordable turbidity meters without compromising quality.
  • Complies with EPA 180.1 and GLP
  • Superior accuracy and precision with Xylem’s IRPC feature.
  • Compact turbidity meter, occupying minimal benchtop space in your lab.
