The present invention relates to a device for measuring the antimicrobial activity of a gas and a method for measuring the antimicrobial activity of a gas. The present invention can be used as a standardized device for measuring the antimicrobial activity of a gas or as a standardized method for measuring the antimicrobial activity of a gas as the present invention is capable of constantly maintaining the concentration of a gas and identifying the growth and development of microorganisms objectively through a color change of a microorganism culture medium containing a pH indicator.La présente invention concerne un dispositif de mesure de lactivité antimicrobienne dun gaz et un procédé de mesure de lactivité antimicrobienne dun gaz. La présente invention peut être utilisée en tant que dispositif standardisé pour mesurer lactivité antimicrobienne dun gaz ou en tant que procédé standardisé pour mesurer lactivité antimicrobienne dun gaz, la présente invention permettant de maintenir en permanence la concentration dun gaz et didentifier la croissance et le développement de micro-organismes de manière objective par un changement de couleur dun milieu de culture de micro-organismes contenant un indicateur de pH.본 발명은 기체의 항균력 측정장치 및 기체의 항균력 측정방법에 관한 것이다. 본 발명은 기체의 농도를 일정하게 유지할 수 있고, pH 지시약을 포함하는 미생물 배지의 색변화를 통해, 객관적으로 미생물의 생육을 확인할 수 있어, 표준화된 기체의 항균력 측정장치 또는 기체의 항균력 측정방법으로 이용할 수 있다.
