Turbidity is scattering of incident light by a particle at right angle. The light is measured by a photodiode. In water any particle for example Silt, sand, bacteria, spores, and chemical precipitates and not color will cause scattering of light.

TN500 Portable White Light Turbidity Meter Kit, EPA 180.1 Compliant

Apera TN500 uses tungsten filament lamp as the light source and 90° scattering method, which is compliant with U.S EPA 180.1 method for the determination of turbidity in drinking, ground, surface, and saline waters, domestic and industrial wastes. The instrument is designed for water quality professionals, offering long-term reliability in high-accuracy turbidity measurement with an intuitive operation system, simple calibration, and GLP data management.

2100Q Portable Turbidimeter

Easiest calibration and verification with accurate results every time.

Measuring and monitoring turbidity is crucial for various industrial and municipalapplications, and Hach’s portable turbidimeter, the 2100Q, provides unsurpassed ease of use and accuracy. With over 80 years of experience, Hach is a leader inturbidity measurement and has consistently developed reliable and durable instruments for customers.

TU5200 Laboratory Laser Turbidimeter without RFID, EPA Version

The next standard in the evolution of turbidity

The platform 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 from test to test. For the first time you will be able to remove the uncertainty of which measurement to trust, thanks to identical 360° x 90° Detection Technology in both instruments. The TU5 Series dramatically reduces the time needed to get a turbidity measurement you can rely on. The TU5200 Lab Turbidimeter, with the 360° x 90° Detection Technology, sees more of your sample meaning you no longer have to apply silicone oil to your vial and index to ensure an accurate reading. In addition, you can have confidence that you will get consistent results in the lab, from operator to operator, since the impact of small interferences is minimized due to the collection of light at 360°.


The TU5 Series employs a patented 360° x 90° 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.

The online TU5 Series instruments come with a variety of options to make maintaining your instrument even easier including:

  • Flow Sensor – identification of flow rate through your turbidimeter
  • Automatic Cleaning Module (ACM) – automatic cleaning of the sample cell
  • System Check – notification of sample cell health
