Application
Application of 7755 AZ CO2 Meter:
The 7755 AZ portable CO2 detector could measure the indoor air quality index, including the CO2 concentration,
CO2 level, CO2 level, air temperature, dew point, wet bulb temperature and humidity. The Carbon Dioxide value
can be output to PC for on-line analysis. The CO2 sensor can be calibrated easily in the fresh air, and the RH
sensor could be calibrated with AZ 33%/75% salt bottle.
The 7755 AZ CO2 device could be used as the CO2 checker for the air quality index in all workspace, 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 7755 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. It is also suggested in regulations of industrial hygiene in some countries.
