WHAT IS THE IMPORTANCE OF CO2 MONITOR? CO2 is not an air pollutant, but it can still have a negative effect on us when levels are too high. When levels rise, we tend to get sleepy and have trouble focusing, and some people even develop headaches. In order to achieve this, they would have to set the sensor to 15% above 1,000 ppm, or about 1,150 ppm. Note that while CO2 sensor modules do not account for changes in altitude from sea level, some CO2 meters have built-in barometers that can compensate in real time. So if you are at high altitudes and need extremely accurate CO2 level 6 hours ago Please subscribe!

Een CO2-meter heeft een nauwkeurige aanduiding van CO2-waardes in parts per million (PPM). De CO2-melder zal in alarm gaan bij een gevaarlijk hoge CO2-concentratie. Daarnaast heeft ze ook een LED-indicator voor de algemene toestand van de ruimte: groen (alles in orde), oranje (verbetering mogelijk) of rood (ongezond hoog). Wat zijn nu normale PPM waarden? 450 tot 800PPM: De ruimte is goed geventileerd.
De CO2 meter heeft 3 LED's die dienen als indicatoren van het aanwezige CO2 gehalte (Groen: < 800 ppm, Oranje: 800-1200 ppm, rood: > 1200 ppm). Wanneer het CO2 gehalte te hoog wordt gaat er automatisch een geluidsalarm op de CO2 meter af. Formula: concentration (ppm) = 24.45 x concentration (mg/m 3) ÷ molecular weight For example: 50 mg/m 3 of NH 3 (17.03 g/mol) 24.45 x 100 ppm / 17.03 = 71.785ppm
