Turbidity is equal to the reduction of the transparency of a liquid due to the presence of particles in suspension. It can be measured by passing a beam of light through the sample. Turbidity is determined by measuring the light that is diffused by the particles in suspension.
The American standard is referred to as the USEPA method and recommends using a visible light source. The European standard subscribes to the Infrared method which has the advantage of being less sensitive to the colour of the samples. HANNA Instruments turbidity meters use both methods and are equipped with a 90° angle sensor.
