Turbidity is a measure of water clarity; how much the material suspended in water causes light passing through the water to be scattered. The higher the intensity of scattered light, the higher the turbidity. Suspended materials in the water are for example soil particles (clay, silt, and sand), micro- organisms (phytoplankton, zooplankton) and other substances.
Turbidity is measured in Nephelometric Turbidity Units (NTU). Turbidity measured in NTU uses nephelometric methods that depend on passing specific light of a specific wavelength through the sample. The measurement is qualitative and cannot be correlated directly as micrograms per liter of suspended solids. The Turbidity sensor BT88i measures turbidity in the range between 0 ... 200 NTU. It is delivered with one empty cuvette and one cuvette containing 100 NTU StablCalFormazin Standard, which is used to calibrated the sensor.
• The measurement of turbidity is a key test of water quality. Compare the turbidity of water sample from various locations.
• Determine the rate of settling of a sample.
• Measure the formation of a precipitate.
The Turbidity sensor can be directly connected to the analog BT inputs of the CMA interfaces. Attention:
The sensor cable BT - IEEE1394 needed to connect the sensor to an interface is not
supplied with the sensor and has to be purchased separately (CMA Art. Nr BTsc_1).
