Reaction material cartridge for measuring outdoor air penetration rate and device for measuring outdoor air penetration rate of substrate, including same

A device for measuring an outdoor air penetration rate of a substrate, which comprises a measuring unit comprising:

• an outdoor air environment control chamber which controls an environment of supplied outdoor air;
• a supply pipe which supplies the outdoor air controlled with the environment;
• a substrate mounting portion located in a first predetermined space of the supply pipe, on which the substrate to be measured with a penetration rate is mounted;
• and
• a cartridge mounting portion located in a second predetermined space of the supply pipe, on which a reactant cartridge which comprises a reactant which reacts according to a contact with outdoor air which penetrates through the substrate is mounted,
• wherein the measuring unit measures a change of the reactant according to the contact with the outdoor air.
