Application of AZ 7788 CO2 & Temperature & Relative Humidity Monitor:
The 7788 AZ indoor air quality monitor could measure the indoor air quality, CO2 value, air temperature and humidity. It also could display the real time clock and calendar, so the 7788 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 7788 AZ CO2 Temperature RH Instrument has the super big LCD to be the CO2 Monitor for the air quality index in all workspace, office, hospital, school, station or home. User could use the relay function to control or transfer the data to the following related instruments. The 7788 AZ CO2 & Temperature & Relative Humidity Meter is your best choice as the air quality testers.
AZ 7788 CO2 & Temperature & RH% Meter was being designed and manufactured by AZ Instrument, a well experienced manufacturer for Environmental Measuring Instrument.
