Description

Compact air quality measuring device for evaluating the concentration of carbon dioxide (CO2), incl. temperature and ambient humidity display
Suitable for indoors (e.g. living room, bedroom, children's room and office)
CO2 air quality display with the following fields: GOOD (green field = good air quality), NORMAL (yellow field = normal air quality) and POOR (red field = poor air quality)
Additional alarm sound at the red warning level of 1001 to 2000 ppm, which becomes more intensive as the quality deteriorates: provides a reminder to ventilate in order to reduce high carbon dioxide levels and therefore avoid difficulties concentrating, headaches and fatigue
Stores the minimum and maximum measured values of the CO2 concentration, temperature and ambient humidity
Temperature indicator can be switched between degrees Celsius and degrees Fahrenheit
Display of the ambient humidity in per cent
The rechargeable battery allows the device to be operated for up to 3.5 hours without a power supply
Battery status bar in 4 bars
