6.4. 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
Cow milk
Sheep milk
Buffalo
*These values depend on the geographical region, the breed and on other
factors.
Milk conductivity changes on the concentration of ions in the milk:
6.5. Conductivity calibration
Menu > Settings > Conductivity > Calibration Co meter
Following message is displayed:
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 25С.
