Application

Application of 77532 AZ CO2 Meter:
The 77532 AZ portable CO2 detector could measure the indoor air quality index, including the CO2 concentration, CO2 level and air temperature. The Carbon Dioxide value can be output to PC for on-line analysis.

The 77532 AZ CO2 device could be used as the CO2 checker for the air quality index in all work space, office, hospital, school, station or home. It can be calibrated easily in the fresh air and its back light function could let user operate in the dark area. The 7752 AZ is your best choice as the indoor air quality (IAQ) testers.

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.
