The Turbidity Meter measures the scattered light caused by particles:

• 90° measuring angle
• Red light 650 ± 30 nm 
• Formazin calibration standard

Particles smaller than 1 µm, such as proteins, mainly cause scattered light and are measured under 90º. Particles larger than 1 µm, such as diatomaceous earth and yeast, mainly cause forward-scattered light and are measured under 25º. Up to 10 calibration curves can be programmed and with product identification and memory, the Vos Rota allows for the traceability of measuring data. A sample (cuvette or bottle) is placed in the measuring chamber, which is filled with water. The automatic measurement proceeds, positioning the sample and rotating it, making 100 measurements, and calculating the average value. The measurement results can be exported to a PC and/or directly printed.
