1. Battery label: Battery charge level
2. TVOC: Total Volatile Organic Compounds in mg/m³.
Substances containing hydrocarbons that evaporate at
low temperatures. Values above 10 mg/m
unacceptable for hygiene. Noticeable effects are lack of

headaches.
3. AQI: Air Quality Index

5. ANEW: Data cleansing and new measurement
6. RESET: Instrument calibration
7. HCHO: Formaldehyde concentration in mg/m³ (HCHO =

HCHO: Formaldehyde is an organic chemical compound with
the molecular formula CH₂O. Under standard conditions
formaldehyde is a gas with a pungent odour. According to the
European Union, formaldehyde can increase the risk of cancer.
The Federal Institute for Risk Assessment (BfR) has set the
tolerable concentration for CH₂O at 0.1 ppm, corresponding
to 0.124 mg/m³.
8. CO2: Carbon dioxide concentration in ppm (parts per million
=
1 millionth = 1 ppm = 10
Federal Environment Agency recommends letting fresh air
into the room from outside if a value of 1,000 ppm CO₂ is
exceeded.
9. CO: Carbon monoxide concentration in ppm. In unventilated
rooms with gas burners, fireplaces or cigarette smoke, higher
values are quickly reached. If the CO concentration rises to
values between 136 and 280 ppm, fatigue, dizziness and
nausea occur after only two to three hours. A value of 368
ppm or more is considered to be unhealthy exposure, higher
values are considered to be directly life-threatening.
