av M Eriksson · 2017 — CO2-koncentrationen i utomhusluften ligger på omkring 400 ppm (parts per million), Rekommendationer för partiklar större än 0,02 mikrometer ligger på 4000.

The CO2 meter shows carbon dioxide concentrations up to 9999 ppm, temperatures from -10… 50 °C, and relative humidity values from 20 … 95%. On the 3.5" display of the CO2 meter, the corresponding values can be read off directly, and the color of the CO2 display changes to provide an objective statement about the quality of the room air based on the CO2 content.

CO2 Controllers, PPM Monitors. CO2 levels in the air are measured in ppm (parts per million). Ambient air has about 300 PPM, but plants benefit the most when the CO2 is between 1,000 and 1,500 ppm. CO2 monitors measure the amount of CO2 in the air so that this can be optimized.

De CO2 air indicator is niet alleen makkelijk in gebruik, maar door ventilatie op basis van het CO2 gehalte, voorkomt het een slechte luchtkwaliteit in uw woning. De CO2 meter geeft via een duidelijk scherm het CO2 gehalte en Concentration percentage unit conversion between part per million and milliliter/m3, milliliter/m3 to part per million conversion in batch, ppm ml/m3 conversion chart Se hela listan på airsain.nl Handheld CO2, Humidity and Temperature Meter - Rotronic CP11 Economical Measurement of Indoor Air Quality. Features.

Now, because i want to build a CO2 meter, let's try to calibrate this sensor for measure CO2. For CO2, if we measure points graph and do power regression we can obtain the function ppm = 116.6020682 (Rs/Ro)^-2.769034857
