Milwaukee Martini Mi-415 Turbidity Meter
Turbidity refers to the
concentration of undissolved, suspended particles present in a liquid.
Turbidity is a measure of the clarity of a sample.
For potable water applications
turbidity is a good indicator of water quality.
Turbidity Measurement is
achieved by analyzing the amount of light refracted from suspended
particles such as clay, silt and organic material.
By measuring turbidity, by
photometric or tube methods, it is possible to estimate suspended solids
content.
Mi415 has two operating ranges
; 0.00 to 50.00 FNU, and 50 to 1000 FNU that can accommodate the most
turbid condition may encounter.
The cloudy appearance of water (called
Turbidity) is caused by suspended material.
The unit of measure adopted by the
ISO Standard is the FNU (Formazine Nephelometric Unit) and by EPA is NTU
(Nephelometric Turbidity Unit)
The other two methods used to test
the turbidity and their measurement units are the JTU (Jackson Turbidity
Unit) and the Silica unit (mg/L SiO2)
