TL23 Series Laboratory Turbidimeters

The TL23 Series ensures stable readings and accurate analysis by capturing turbidity readings once the device detects sample stability. This quality step removes subjectivity and the need for repeated measurements.


The TL23 Series benchtop turbidimeters for a wide range of turbidity applications feature the trusted technology of Hach’s legacy benchtop turbidimeters and improved functionality to simplify testing. These features include a colour touch screen, a USB port for data transfer, self-diagnostics for quality assurance, and single point calibration for measurements under 40 NTU/FNU.

The TL23 Series benchtop turbidimeters are available in four different models: two models with tungsten lamp at 460 nm, and two models with LED light source at 860 nm.
