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.
Just like the legacy instrument, the TL23 lab turbidimeter comes in 4 different models:
- 2100N is replaced by TL2300 (EPA, up to 4,000 NTU)
- 2100NIS is replaced by TL2310 (ISO, up to 1,000 NTU)
- 2100AN is replaced by TL2350 (EPA, up to 10,000 NTU)
- 2100ANIS is replaced by TL2360 (ISO, up to 10,000 NTU)
With their ratio technology, the TL23 lab turbidimeters are ideal for industrial and other samples with a wide range of turbidity. The main benefit of TL23’s ratio technology is that it helps to overcome the interference from large particles and color when measuring turbidity.
Principle of Operation
TL2300 and TL2350 Turbidimeters: The optical system is comprised of a tungsten-filament lamp, lenses and apertures to focus the light, a 90° detector, forward-scatter light detector, a backscatter detector (TL2350 only) and a transmitted-light detector. The instrument permits turbidity measurements at less than 40 NTU to be performed using only the 90° scattered-light detector or from 4000 NTU (TL2300) to 10000 NTU (TL2350) using the complete set of detectors (Ratio Measurement). With the Ratio Measurement on, the instrument’s microprocessor uses a mathematical calculation to ratio signal s from each detector. The benefits of using Ratio on for measurements include excellent linearity, calibration stability and the ability to measure turbidity in the presence of color.
TL2310 Turbidimeter: The optical system includes an 860 ±30 nm light emitting diode (LED) assembly and a 90° detector to monitor scattered light. The instrument measures turbidity up to 1000 FNU or NTU using the single 90° detector. The instrument does not utilize ratio measurements.
TL2360 Turbidimeter: The optical system includes an 860 ±30 nm light emitting diode (LED) assembly and a 90° detector to monitor scattered light, a forward-scatter light detector, a transmitted-light detector and a back-scatter light detector. The instrument measures turbidity up to 1000 units in FNU measurement mode using the ratio detectors. Attenuation measurements of up to 10000 FAU units can be made using a single transmitted detector. The instrument measures turbidity at less than 1000 NTU using only the 90° scattered-light detector or up to 10000 NTU using the complete set of detectors (ratio mode).

Environmental Dredging and Remedial Construction
Though dredging is often painted in a negative light, dredging initiatives and projects are often conducted to improve environments, begin recovery periods for water beds contaminated with toxins, and reinvigorate ecological systems and habitats. Many of the technicians and engineers who plan and execute dredging projects are dedicated to balancing the economic benefits of dredging with protecting the environment. Sevenson Environmental Services Inc. provides sediment remediation as one of many key services offered to help restore natural environments. Steven Shaw spent more than a decade working as an engineer on various dredging projects before finding his way to Sevenson eight years ago.

Caring for the Chesapeake: Supporting the Iconic Bay Starts with Good Monitoring Data
The Chesapeake Bay is enormous: the Bay and its tidal tributaries have 11,684 miles of shoreline—more than the entire U.S. west coast. It is the largest of more than 100 estuaries in the United States and the third largest in the world. The Bay itself is about 200 miles long, stretching from Havre de Grace, Maryland, to Virginia Beach, Virginia. But the Chesapeake Bay isn’t just enormous--it’s enormously important. The Chesapeake Bay Program reports that its watershed covers about 64,000 square miles and is home to more than 18 million people, 10 million of which live along or near the Bay’s shores.

Treating Harmful Algal Blooms: A Natural Progression
Some of us happen upon the subject of our life’s work by accident, some of us are born into it, and some of us ease into it over time. For Tom Johengen, Research Scientist for Cooperative Institute for Great Lakes Research (CIGLR) and Director of Michigan Sea Grant , choosing to study Harmful Algal Blooms (HAB) was “a natural progression” from his days as a grad student investigating best management practices for controlling nonpoint source nutrient pollution. “I’ve been the research scientist with CIGLR since my postdoc in 1991, 31 years, and I’ve been the Director of Michigan Sea Grant for the past 3 years. When I began my postdoc with CIGLR we were just starting to study the impacts of the recently invaded zebra mussels.
