-The International Organization for Standardization (ISO) developed a design standard known as ISO7027 Water Quality—Determination of Turbidity, which is best known for its requirement of a monochromatic light source. Most instruments that comply with this standard use an 860 nm LED light source and a primary detector at an angle of 90°. Additional detection angles are allowed, such as a detector at an angle of 180°, to increase the range of measurable turbidity levels.+The International Organization for Standardization (ISO) developed a design standard known as ISO 7027 Water Quality—Determination of Turbidity, which is best known for its requirement of a monochromatic light source.

-The demo will use a network of 860nm Infrared emitters and silicon PIN photodiodes to achieve a water turbidity measurement system. The system can measure low to high water turbidity levels ranging from 0 FTU to 1000 FTU.+The demo uses a network of 860 nm infrared emitters and silicon PIN photodiodes to achieve a water turbidity measurement system.
