Environmental Turbidimeters

GAO’s environmental turbidimeters are used to measure the turbidity, or cloudiness, of a liquid sample. Turbidity is caused by the presence of suspended particles, such as sediment, algae, and other substances, which scatter light passing through the sample. GAO Tek’s turbidimeters measure the amount of light scattered by these particles and provide a numerical value of turbidity.

GAO’s environmental turbidimeters are composed of light source, sample cell, detector, optical system, display, power supply, and control system.

The other common names of turbidimeters include turbidity meters, turbidity analyzers, turbidity sensors, turbidity measurement devices, cloudiness meters, haze detectors, suspended solids analyzers, water clarity testers, particulate matter analyzers, sediment concentration meters, murkiness gauges, opacity sensors, haziness detectors, turbidity testers, muddy water analyzers, and filtration monitoring devices.
