This air quality meter has an extra large display!
As a result, the PPM value is always clearly visible. In addition, the time and temperature can also be displayed.

High quality non-dispersive infrared (NDIR) gas sensor with CO2 measuring range up to 5000 ppm Ventilation advice based on CO2 concentration in the air. In addition, this unit also measures air humidity and temperature.

Ideal for public buildings such as hairdressers, schools, gyms, museums, sports clubs, etc. But also just a good way to measure the air quality at home.

Everyone knows how important good ventilation and air quality are.

This air quality monitor warns you to ventilate more if the air quality is not good enough. The quality can be read by the values ​​on the meter. You also receive ventilation advice because the color of the advice block changes.
(The numbers speak for themselves, the text on the meter is in German)

CO2 levels and guidelines
Below are some general CO2 reference levels:

Background (normal) outside air level.

Typical level for occupied spaces with good air circulation.

Start ventilation of the room.

Level associated with complaints of drowsiness and bad air.
Ventilation recommended!

Level associated with headache, drowsiness and stagnant, stale, stuffy air. Poor concentration, loss of attention, accelerated heart rate and mild nausea may also occur.
Ventilation highly recommended!

> 5.000 ppm
Exposure can lead to severe oxygen starvation, which can lead to permanent brain damage, coma and death.
Requires immediate ventilation!

Before first use:
The values ​​are displayed within 2,5 minutes. It will then calibrate the device (automatically) for another 24 hours and then display accurate readings. This process is repeated when you move the device, for example to measure the air quality in another room. This process enables the Technoline Air Quality Meter to guarantee accurate measurements.
