Indoor Air Quality Transmitter AVC-M Series In most public space or office buildings, the air ventilation and air quality is poor. The AVC-M series can detect several important parameters of indoor air quality and environment, such as CO2, CO, HCHO, O2, NH3, TVOC, PM2.5, PM10, temperature and humidity. Easy installation and the recommended height of installation is 1~2M above the floor level. It uses good quality sensors; such as the NDIR CO2 sensor; electro-chemical sensor for HCHO, CO, O2 and NH3; laser scattering principle sensor for PM2.5 and PM10; CMOS sensor for TVOC, temperature and humidity. AVC-M can be used with a monitoring system, which can activate ventilation system to keep a better indoor air quality or for energy saving. It is perfect for school, library, offices, meeting room, commercial building, shopping center, train/subway station or exhibition hall, etc.
