3) PM (Particulate Matter) display mode: Simultaneously displays

PM2.5 and PM10 measurement values.

4) VOC (Volatile Organic Compound) display mode

VOC concentration is displayed together with the ppm unit figures.

5) CO2 display mode

CO2 concentration is displayed in graph form.

The CO2 sensor applied to our product is CO2eq (CO2 equivalent),
which is calculated based on the H
when breathing in the fasting state.
It may react to other harmful gases in the surrounding environment.
If it shows a poor/unhealthy condition, use it as a ventilation
guideline for indoor air management.

**** In case of CO2 and VOC, the value is displayed after 15 ~ 60
seconds at power-on, after which the value is updated in every
second.

6) Temperature/Humidity mode

It shows temperature and humidity in one screen.

*** In case of temperature and humidity, the temperature/humidity
sensor is inside of the product and may cause a deviation of
5 ~ 10%.
