ABSTRACT:
A measuring apparatus for measuring the charging degree of a liquid is provided with a casing accommodating an insulating material in the middle of a circulating system in which a base liquid is circulated.
The charging degree of a test liquid is measured by the change of a charging quantity when the test liquid is injected by a syringe in the circulating system while a charging quantity which occurs from friction between the insulating material in the casing and the flowing base liquid is detected.
