Is the measurement range of the carbon dioxide detector as large as possible?
Carbon dioxide optional reference classification:
(1) 250~350ppm—the usual outdoor air level.
(2) 350~1,000ppm—a typical value in a well-ventilated living space.
(3) 1,000~2,000ppm—the level of oxygen-deficient, drowsy air that causes complaints.
(4) 2,000~5,000ppm—the level of stagnant, stale, stuffy air. Headache, drowsiness, along with difficulty concentrating, decreased concentration, racing heart, and mild nausea.
(5) > 5,000 ppm—Exposure may be severely deprived of oxygen, resulting in permanent brain damage, coma, and even death.
At present, carbon dioxide detectors on the market have a measurement range from 0-100% VOL.
Low concentration: from 0-2000ppm/3000ppm/5000ppm/10000ppm, (1ppm is the gas unit, 1ppm refers to the volume ratio of one millionth.)
High concentration: from 0-5%/10%/20%/40%/50%/100%VOL. (%VOL is volume ratio)
The relatively large measurement range is 100% VOL, that is to say, the space is full of carbon dioxide.
To sum up, we can see that the measurement range of the carbon dioxide detector is not as large as possible. Its measurement range needs to be selected according to your on-site gas concentration to have more accurate detection results. Specific suggestions You consult the professionals of Yiyuntian, and they will make a reasonable choice for you according to your requirements and combined with the site of use.
