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).

Applied Research and Innovative Solutions: Creating CHNGES at Western Kentucky University
Long-standing environmental monitoring programs have the power to support a large number of research initiatives and policy changes—however, actually starting these networks can prove challenging. Not only is starting the program difficult, but keeping things operational for decades to come has also been challenging for environmental professionals hoping to make an impact with applied research. Jason Polk, Professor of Environmental Geoscience and Director of the Center for Human GeoEnvironmental Studies (CHNGES) at Western Kentucky University, is all too familiar with this process.

Combating Water Insecurity in Saskatchewan with Real-Time Data
The prairies of Saskatchewan can be described as one of the least water-secure parts of Canada, making water quality monitoring essential for informed resource management in a region already facing water insecurity. While natural physical properties worsen some of the poor water quality conditions in the region, others are connected to land use. Having grown up spending summers on the shores of Lake Huron, Helen Baulch, an associate professor at the School of Environment and Sustainability at the University of Saskatchewan , has always been dedicated to the protection of water resources. Looking back fondly at her childhood playing along the shore, Baulch also recalls the invasion of quagga mussels during her teenage years and watching the lake change as a result.

Seametrics Turbo Turbidity Logger: Boost your Turbidity Monitoring
The Seametrics Turbo Turbidity Logger is a self-cleaning turbidity sensor capable of internally logging over 260,000 data records. The sensor enables researchers, compliance officers, and contractors to monitor turbidity in various applications, from construction and dredging sites to wastewater effluent. Due to its narrow width, this device can be deployed in a range of areas, from small well spaces to rivers and streams. The stainless steel housing and built-in wiper allow the sensor to withstand long-term deployments and reduce the need for maintenance trips. The logger accurately records temperature and turbidity up to a depth of 50 meters.
