CLIMASET s.r.l.<\/span> offers the T, H and IAQ CAREL sensors for offices, houses, shopping malls, wherever there is a need to monitor building indoor air quality<\/b>.<\/p>\n

With these sensors it is possible to measure:<\/p>\n

    \n
  1. temperatures <\/b>and relative humidity<\/b> values,<\/li>\n
  2. carbon dioxide<\/b> (CO2) concentration,<\/li>\n
  3. VOC <\/b>concentration, also known as volatile organic compounds<\/b>,<\/li>\n
  4. PM2.5<\/b> and PM10<\/b> concentrations, also know as particulates<\/b>.<\/span><\/li>\n<\/ol>\n

    The probes could show the current value using a display or they can share the value with other devices, by using a proportional signal or with the RS-485 serial communication.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    Why monitoring indoor air quality?<\/h2>

    New and recently renovated buildings<\/b> are usually good insulated <\/b>and energy efficient, but they tend to need constant air exchanges<\/b>. Furthermore, people tend to stay indoors the majority of their time (houses, offices, shopping mals, etc).<\/p>

    The accumulation of VOC and of other substances, such as particulate, could have negative effects on\u00a0 health<\/b>, on the productivity <\/b>and lower the level of comforts: monitoring the air quality<\/b> and insuring its constant exchange, by using systems such as the controlled mechanical ventilation (CMV) is therefore a priority<\/b>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    Recomendations and limit values<\/h2>
    The European Union has recently published its new DIRECTIVE (EU) 2024\/288<\/b> <\/b>with\u00a0 its list of limit values pertaining indoor air, for example see these parts of the directive:<\/div><\/div><\/div>
