Application
Application of 7721 AZ CO2 Meter:
The 7721 AZ Wall Mount CO2 detector could measure the indoor air quality (IAQ) index, including the CO2
concentration, CO2 level and air temperature. 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 7721 AZ CO2 device has the relay function, which could transfer the signal to control the other equipment.
The 7721 AZ CO2 meter has the stable NDIR CO2 sensor, and it is the ideal instrument for IAQ diagnosis.
Its big LCD could be the best CO2 Monitor for long term monitoring. 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.
