Application
1.
Crude oil and petroleum products
Density/SG of crude oil, fuel oil (heavy oil, light oil, kerosene, gasoline) or lubricant is measured
to obtain reference value for product pricing or taxation.
2.
Chemical products
Density/SG is important for quality control and management in chemical industries. For organic
substance of petroleum industry, it is used for QC of intermediate and finished products, and for
inorganic substance of heavy chemical industry, it is for purity control or concentration check.
Test method for density at 20
°
C or SG at 20/20
°
C is specified by JIS K 0061.
3.
Beverages
Density and Brix are measured for QC or line control of milk, dairy products, soft drinks,
carbonated drinks, fruit juice or soy milk.
4.
Alcoholic beverage
For beer, sake, whisky, brandy, wine, distilled spirit, etc.: alcohol degree or concentration of
extract is used in quality control. The alcohol degree is used in taxation.
5.
Food
Brix concentration is used in QC of food material like honeydew, extracts, saline solution, syrup
or isomerized sugar. Brix is also used for QC of soy sauce, cooking sauce or gravy.
6.
Fat and oil
Density/SG is used for quality control of plant oil or animal fat.
7.
Pharmaceutical products
Japanese pharmacopoeia specifies QC and R&D by density measurement.
8.
Flavour, fragrance, chemical products
Density and refractive index are used for QC in perfumery. Your density meter can be connected
to KEM’s refractometer.
9.
Electronic devices, semiconductor
Density is used for QC of surface finishing material like etching solution or pickling.
10.
Electrics
Density is used for control of flux concentration or plating solution in production line.
11.
Others
Density, SG or Brix is used in quality control or concentration control of various liquid products.
