    摘要: A neutralization testing apparatus and a neutralization testing method which allow a neutralization reaction rate of a liquid sample such as lubricant oil to be accurately measured are provided. Reagent injecting device for injecting a reagent which neutralizes the liquid sample is provided on a lid member of a closed container into which the liquid sample is charged. The reagent injecting device is an acid injecting port which penetrates through the closed container and an air-tight sealing member which closes the acid injecting port and which permits an injector needle for injecting the reagent to penetrate therethrough. Because no gas leakage occurs even when the injector needle is penetrated because of the elasticity of the air-tight sealing member, the measuring conditions within the closed container do not change and the neutralization reaction rate may be found accurately.
