The present invention relates to an inhalation toxicity testing chamber device for nanoparticles having a plurality of concentrations. The present invention provides an inhalation toxicity testing chamber device for nanoparticles having a plurality of concentrations, which: can supply nanoparticles having different concentrations to particle exposure modules by stacking a plurality of particle exposure modules inside a single chamber housing and by allowing each particle exposure module so as to form an independent space from each other; can perform inhalation toxicity testing of nanoparticles having a plurality of concentrations through a single chamber housing by being capable of exposing the test animals put into each particle exposure module to nanoparticles having different concentrations; can easily perform inhalation toxicity tests of nanoparticles in a small scale laboratory etc. by improving the overall space efficiency as well as reducing the test cost; and can easily perform more diverse and accurate inhalation toxicity tests on nanoparticles by selectively allowing a plurality of particle exposure modules to be in communication with each other or to be formed as an independent space, according to a user's needs, thereby variably applying the space of the particle exposure module without changing the arrangement of the particle exposure module.
