Mix Gases (TVOC-Total Volatile organic compound）
VOC emitted from building materials, decoration materials and furniture, includes toluene, ammonia, H2S, formaldehyde and other harmful gases. Its necessary to real time detect these harmful gases. But it’s costly to use the professional instruments to detect each single gas. Also it’s possible to monitor for daily use. These gases exit in air for a long time and their volatilization level are different in different temperature and humidit
