Hama "Safe" mobile air quality meter

Compact air quality meter to determine the concentration of carbon dioxide (CO2), with temperature and humidity indicator.

The air quality meter helps you live and work healthy. So you can find the right balance between ventilation and heating for a healthy indoor climate and your well-being.

Precise and reliable: CO2 measurement with NDIR sensor and measured values in ppm.

With the easy-to-understand traffic light indicator, you will know at a glance what the air quality is like in your rooms: CO2 air quality indicator with the following fields: GOOD (green field = good air quality), NORMAL (yellow field = normal air quality) and BAD (red field = poor air quality).

Additional alarm tone at the red warning level from 1001 to 2000 ppm, which becomes more intense as the deterioration increases: reminds you to ventilate the room to avoid high levels of carbon dioxide and therefore problems with concentration, headaches and fatigue.

Battery operation and compact dimensions allow the air meter to be used in different rooms

Suitable for all interior spaces (for example, office, living room, bedroom, children's room, mobile home, caravan and motorhome)

Stores the minimum and maximum measured values of CO2 concentration, temperature and humidity

Switchable temperature display between Celsius and Fahrenheit

Indication of humidity in percentage

Rechargeable battery allows unit to run for up to 3.5 hours without power

Battery status bar in 4 bars

Consumer Tips: The CO2 concentration can be used to draw conclusions about airborne aerosols, for example, viruses such as the Novel Corona virus (SARS-CoV-2). Regular intermittent ventilation is recommended if the CO2 level is indicated to be elevated.

Disclaimer: The meter is not to be used as a warning indicator of dangerously high concentrations (eg occupational health and safety monitoring). It is not suitable for medical facilities, certification, or test measurements. The measuring device is primarily used for testing and guidance in private use. No liability is assumed for possible damages in case of incorrect operation. Data transfer via USB cable is not possible.
