OPTIQUAD –Inline Analyzer
in the cheese making milk/vat milk, standardization of fat content in drinking milk or setting a constant ratio of fat to protein in cheese production. OPTIQUAD WW is used for continuous inline measurement of chemical oxygen demand (COD) in dairy wastewater. Unlike other COD analysis systems that typically use one optical principle and one wavelength, the OPTIQUAD WW uses up to four optical principles and up to twelve wavelengths. This results in an accurate, stable measurement over a broad measuring... (read more)
