PolyGard^® Indoor Air Quality and Room Control for urban spaces  
  
The most important point for the air quality in closed rooms like offices, living spaces or class rooms is the purity grade of the air. Poor air restricts the well-being and has negative influences on the productivity and/or the efficiency of manufacturing processes. The climate is often controlled via temperature, humidity and CO₂ mesurements. Most people, however, judge the air quality on the basis of the quantity of Volatile Organic Compounds (VOCs) like cigarette smoke, kitchen odors, human emanations and air pollution. In general, temperature and humidity are easy to determine. CO₂ measurements, however, have always been very expensive so far and VOC measurements have been difficult to realize.
 
Thanks to the IAQ transmitter by MSR Electronic, the air quality can be measured close to the human perception. The device indicates reliably if the air isn't good any longer and transmits the necessary information to the heating, air conditioning or ventilation system. Due to the individual options and setting possiblities for the temperature and humidity measurements, the IAQ transmitter by MSR Electronic is ideal for many applications.
