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

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

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.

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.

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.
