AZ 7729 Backlit Display Indoor Air Quality Monitor

AZ 7729 Backlit Display Indoor Air Quality Monitor

• AZ 7729 is an indoor air quality monitor capable of measuring carbon dioxide levels between 0 and 9999 ppm.
• It displays CO₂, temperature, and humidity values simultaneously on a single screen.
• The device measures temperatures from -10°C to 60°C and humidity from 0.1% to 99.9% RH.
• You can set alarm levels between 800 and 3000 ppm. The device features visual and audible alarms.
• Values below 800 ppm are considered healthy; 800–1000 ppm are slightly above average; above 1000 ppm indicates a poorly ventilated area.
• As CO₂ levels increase, the screen color changes:
  • Below 800 ppm → Green,
  • 800–1000 ppm → Yellow,
  • Above 1000 ppm → Red
• High CO₂ levels in crowded areas (schools, meeting rooms, offices, etc.) can cause headaches and difficulty concentrating.
• The fully touchscreen interface allows for easy operation.
• The large LCD screen with backlight ensures visibility even in dark environments.
• Equipped with a desktop stand and wall mounting holes on the back.
• Hold the SET button to access settings.
• Alr: Set CO₂ alarm threshold.
• Uni: Switch temperature unit between °C / °F.
• bur: Enable/disable alarm sound (requires restart to activate).
• abc: Automatic background calibration.
• bl: Warning light brightness (adjustable from 1 to 10).
• Press and hold SET and MUTE/+ to enter calibration mode.
