Application of AZ 7722 CO2 & Temp. & RH meter:
The 7722 AZ Wall Mount CO2 Humidity detector could measure the indoor air quality (IAQ) index, including the CO2 concentration, CO2 level, air temperature, dew point, wet bulb temperature and humidity. The Carbon Dioxide value can be output to PC for on-line analysis via USB interface. And it can be calibrated easily in the fresh air.
Poor indoor air quaintly is considered unhealthy because it causes tiredness, loss of ability to concentrate, and even illness (ex: sick building syndrome). IAQ monitoring and survey, especially on CO2 level and air ventilation become widely applied in public areas such as office, classroom, factory, hospital, work space, residential, commercial building and hotels. It is also suggested in regulations of industrial hygiene in some countries.
The 7722 AZ CO2 RH Thermometer device has the relay function, which could transfer the signal to control the other equipments.

User could use the relay function to control or transfer the data to the following related instruments. And the built-in alarm output is especially helpful in ventilation control and HVAC system performance verification.
