At present, in our daily life, although the application of carbon dioxide is very extensive, once it is excessive, it will also have serious harm to the human body and the environment. However, the carbon dioxide detector is the 1 instrument for monitoring carbon dioxide gas. It adopts a dual-beam, dual-wavelength infrared detector, which makes the instrument more accurate in the detection process, improves the resolution of the instrument, and has extremely strong stability. Then in the process of selection, is the measurement range of carbon dioxide detector the larger the better? The following is a brief introduction by yi yun Tian:

The measuring range of the CO2 detector is not as large as possible.

Non-mandatory reference classification for carbon dioxide:

(1) 250 to 350ppm-usual outdoor air levels.

(2)350 to 1,000ppm-typical values in well-ventilated living spaces.

(3) 1,000 to 2,000ppm-the level of air that is oxygen-poor, sleepy enough to cause complaints.

(4) 2,000 to 5,000ppm-stagnant, old, stuffy air levels. Headache, lethargy, accompanied by lack of concentration, decreased attention, rapid heartbeat and mild nausea.

(5) & gt; 5,000 ppm-Exposure can cause severe hypoxia, resulting in permanent brain damage, coma and even death.

At present, the measurement range of carbon dioxide detectors on the market ranges from 0-100% VOL.

low concentration: from 0-2000ppm/3000ppm/5000ppm/10000ppm,(1ppm is the gas unit, 1ppm refers to the volume ratio of 1 per million.)

High concentration: from 0-5%/10%/20%/40%/50%/100 VOL. (%VOL is volume ratio)

The larger measurement range is 100%VOL, that is, the space is full of carbon dioxide.

to sum up, we can see that the measuring range of the carbon dioxide detector is not the larger the better. its measuring range needs to be selected according to your on-site gas concentration to have more accurate testing results. for specific advice, you should consult professionals in yiyuntian, they will give you a reasonable choice according to your requirements and in combination with the use of the site.
