What is a Turbidimeter?
Turbidimeters, also called turbidity meters, are instruments used for measuring the turbidity of liquids.
The turbidity of a sample is proportional to the intensity of the light reflected by particles in the water.
Turbidity is a measure of cloudiness in liquids and has been recognized as a simple and basic indicator of water quality.
Types of Turbidimeters
Hach offers turbidity meters for a wide range of applications:
- Portable turbidimeters offer convenient measurements in the field.
- Laboratory benchtop turbidimeters are used in laboratory settings.
- Process turbidimeters offer the most accurate and continuous measurement of the flowing sample.
Portable Turbidimeters
Field analysis requires a measuring instrument that’s convenient, durable, accurate and able to withstand conditions encountered at the testing site.
Portable, handheld turbidimeters like Hach’s 2100Q, are convenient and offer accuracy that’s on par with laboratory turbidity meters.
It also offers the benefit of simple data transfer with a USB+ power module so you can easily download information for superior data integrity and availability.
Laboratory Turbidimeters
Also called benchtop turbidimeters, lab turbidimeters are used when conducting water analyses from multiple sources, as opposed to testing water samples on-site in the field.
Whether it’s periodic analyses of raw or settled water, calibration of process turbidity analyzers or compliance monitoring, a lab turbidimeter is the best solution for measuring samples from multiple sources.
Laboratory turbidimeters such as the Hach TU5 series, are designed to provide precise and accurate measurements in controlled conditions.
Process Turbidimeters
For drinking water applications and in some wastewater treatment plants, it’s necessary to continuously monitor each step of the filtration process to prevent costly mishaps.
If there is any interruption in the filtration process, an online process turbidimeter can provide an immediate notification in real time.
Hach’s turbidity analyzers and online laser turbidimeters are the best solution when you need an accurate turbidity reading at a moment’s notice.
Featured Turbidimeter Products
Portable Turbidimeter
The 2100Q portable turbidimeter provides convenient data logging. Up to 500 measurements are automatically stored in the instrument for easy access and backup. Stored information includes: date and time, operator ID, reading mode, sample ID, sample number, units, calibration time, calibration status, error messages, and the result.
Shop NowHach’s TSS Portable turbidity/TSS/sludge blanket level probe uses a unique multi-beam alternating light method with infrared diode system that gives it a broad measuring range for both turbidity and suspended solids in one portable hand-held instrument.

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.
Shop NowTU5 Series Laboratory Turbidimeters
The TU5200 is designed to deliver a revolutionary 360° x 90° Detection Technology, engineered to see more of your sample than any other turbidimeter. This unique technology is used in both the TU5 online and TU5 benchtop turbidimeters, allowing you for the first time to remove the uncertainty of which measurement to trust.

Surface Scatter 7 sc High Range Turbidimeter
The Surface Scatter 7 sc High Range Turbidimeter offers superior performance across a measurement range of 0 to 9999 NTU. The Hach Surface Scatter 7 sc Turbidimeter (SS7) is the original non-contact turbidimeter. This design minimizes sensitivity loss due to high turbidity samples; in fluids with high loads of suspended solids the design makes sample cell cleaning and replacement unnecessary.
Shop NowTU5300sc/TU5400sc Online Laser Turbidimeters
The TU5 Series employs a patented optical design that sees more of your sample than any other turbidimeter, delivering the best low level precision and sensitivity while minimizing variability between measurements. Remove uncertainty of which measurement to trust between your lab and process instruments, thanks to identical 360° x 90° Detection Technology.
Shop NowSolitax sc sensors can be connected to all SC controllers, providing versatile output options including 4-20 mA Output, Modbus RS485, Profibus, or Hart. Solitax sc process probes are designed for the accurate determination of turbidity and suspended solids in accordance with DIN EN ISO.
Shop NowHach's TSS sc are digital special probes for determining turbidity and suspended solids in aqueous, and also aggressive, media, in accordance with DIN EN ISO. The TSS sc connect directly to all SC controllers providing versatile output options including 4-20 mA Output, Modbus RS485, Profibus, or Hart.
