Selecting a Turbidity Meter on Amazon.com
Turbidity meters, sometimes called turbidimeters, are used to determine the concentration of solids in a sample of liquid, usually water. Turbidity is the cloudiness of a liquid caused by the presence of suspended solids (particles) that may include microorganisms, yeast, or sediment. Handheld turbidity meters are designed for field use, benchtop models for laboratory use, and inline models for installing directly in a water supply line. Some models provide datalogging or data export to a computer, and most require routine calibration using a standard solution. Meters are often manufactured to meet industry or government standards, including USEPA (United States Environmental Protection Agency) and ISO (International Standards Organization) and are commonly used to test liquids for compliance with government standards for drinking water, environmental water, and water used for food, beverages, and brewing.
