Method of determination.
Conductivity (or Electrolytic Conductivity) is defined as the ability of a
substance to conduct electrical current. It is the reciprocal of the resistance.
In a healthy animal*, the mean value of electric conductivity is:
Milk type
Conductivity values
Cow milk
between 4 to 6,5 mS/cm (25°C);
Sheep milk
between 3 to 5,5 mS/cm (25°C);
Buffalo
between 2,5 to 5,5 mS/cm (25°C);
*These values depend on the geographical region, the breed and on other
factors.
Milk conductivity changes on the concentration of ions in the milk:

Serves for conductivity measuring system calibration. Clean the analyzer
before starting conductivity measurement. You need a standard buffer with
conductivity 5.0[mS/cm], with temperature 25
