G Operating instruction
1. Controls and displays
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
considered unacceptable for hygiene. Noticeable effects are lack of concentration,
exhaustion, dry skin through to eczema or headaches.
3. AQI: Air Quality Index
4. ON/OFF: On/Off button
5. RESET: Data cleansing and new measurement
6. ANEW: Instrument calibration
7. HCHO: Formaldehyde concentration in mg/m³ (HCHO = CH₂O)
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
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.
