The new TL23 Series laboratory turbidimeters blend trusted technology and improved features to simplify testing in the most demanding industrial and wastewater applications.
Hach’s new TL23 lab turbidimeter brings a new face to the trusted legacy 2100N and 2100AN turbidimeters. It utilizes the same optic bloc while delivering an improved user experience with its intuitive interface, which ties perfectly to the rest of Hach’s laboratory instruments.
Having the same optic bloc means that you can replace your old 2100N/AN with a TL23 turbidity meter without having to change any of your standard operating procedures.

Improved and intuitive design
The TL23 Series’ large full color touch screen display and intuitive user interface accelerate setup, calibration and measurement. An easy interface and guided procedures give you confidence in your results.
A smart device for more reliable measurements
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.
Easy to use. Easy to Be Right
The TL23 Series provides everything you need at your fingertips. With a USB port for easy data export, sample identification for traceability, and self-diagnostics for quality assurance, Hach® makes it easy to Be Right.
