Application of AZ 7798 CO2 Data logger:
The 7798 AZ indoor air quality data logger could measure the indoor air quality, CO2 value, air temperature and humidity. It also could display the real time clock and calendar, so the 7798 could be your best IAQ (Indoor Air Quality) Watcher.
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 7798 AZ CO2 Temperature RH Recorder has a super big LCD, which could be use as the CO2 data logger and the real time monitor of air quality index in all work space, office, hospital, school, station or home. The CO2 concentration data could be downloaded to the PC via the USB cable.
AZ 7798 CO2 & Temperature & Relative Humidity Data logger was being designed and manufactured by AZ Instrument, a well experienced manufacturer for Environmental Measuring Instrument.
