The monitor measures the amount of carbon dioxide with light and displays the light on the interface.
The slim, compact design integrates the CO2 monitor and thermometer so that the unit can be placed anywhere you care about the air.
Both USB and household power supplies can be used.
- The CO2 concentration is measured once every seven seconds. The light bar glows during the measurement.
- The ambient temperature can be measured together with the CO2 concentration.
- The three-staged LED display can be recognized at a glance.
- The three-staged LED level can be customized.
- The past 24 hours (48 sets) of logs can be stored.
- The highest and lowest CO2 concentrations during continuous measurement can be recorded.
- In addition to an AC adaptor, a USB connection can also be used as the power supply.
*Relationship between the concentration of carbon dioxide and the human body
It is common knowledge that the increase in carbon dioxide is a factor in global warming. However, the influences on the human body are not yet generally known. Although the concentration of carbon dioxide originally contained in the atmosphere is 400−500 ppm (0.04%−0.05%), it increases in enclosed spaces or places where people gather. Generally when the concentration exceeds 1000 ppm, it causes drowsiness and impaired concentration. In fact, ventilating a room based on this value maintains efficient indoor conditions.
