Abstract  Four low-cost particulate sensors (PT, NF, SF, YT) were utilized as the representatives, comparing with medium-level light-scattering particulate matter monitor (LL).The linear response and parallelism were tested through the high concentration submergence experiment.The results showed that both the linearity of PT and SF sensor were much better than that of YT and NF sensors after the high-concentration submergence experiment.Moreover, the high concentration of dust barely influenced the parallelism of PT and SF.According to the consequences, the high concentration submergence experiment can indeed pick out the defectives to some extent, which indicated that high concentration submergence experiment could serve as a laboratory experiment to simulate extreme environmental conditions experiment for the purpose of pre-market testing.
