Turbidity / Total Suspended Solids (TSS) Analyser

Turbidity or Total Suspended Solids (TSS) is associated with water clarity or haziness. Turbidity measures how much light is scattered by the particles in water and provide a relative indication of water clarity, measured in Nephelometric Turbidity Units (NTU). TSS measures the actual weight of solid particles suspended in a given volume of water, measured in milligrams per litre (mg/L). Particles suspended in the water, usually silt and clay, are responsible for water haziness or cloudiness. Turbidity is a crucial determinant of quality of the water since bacteria and viruses can be attached to these particles This analyser uses an optical method to determine the turbidity or TSS, a light beam is directed into the sample where it is scattered by suspended particles in the water. The amount of scattering depends on the amount of haziness in the water, the wavelength of light used and the size and composition of the suspended solids. It uses a near infrared (NIR) LED light source and the 90° scattered light method in accordance with ISO 7027 / EN 27027 to measure accurate turbidity values. The 90° scattered light detection method is the most common sensor design for the turbidity measurement. Our turbidity sensor has the advantage of a high sensitivity for turbidity throughout the measurement range and a simple optical configuration with an automated cleaning wiper feature.
