Air Quality Meter

Air Quality Meter CO2 Formaldehyde TVOC

Air Quality Meter CO2 Formaldehyde TVOC


Intelligent value tester uses a semiconductor sensor to monitor air quality


Features a superior electrochemical detection module 

with high accuracy, stable performance


Strong anti-interference ability, low power consumption and a long service life


This sensor does not require any calibration, it self calibrates upon booting and can accurately detect the quality levels in seconds


Different colors correspond to overall air  quality at that time


Green 400-450ppm

Blue 451-700ppm

Purple 701-1000ppm

Yellow 1001-2000ppm

Red 2001-5000ppm


Formaldehyde (HCHO) is the most important carcinogen in outdoor air among the 187 hazardous air pollutants (HAPs) identified by the U.S. Environmental Protection Agency (EPA), not including ozone and particulate matter


Carbon dioxide (chemical formula CO 2) is an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. The current concentration is about 0.04% (412 ppm) by volume, having risen from pre-industrial levels of 280 ppm


TVOCs play an important role in communication between animals and plants, e.g. attractants for pollinators, protection from predation,and even inter-plant interactions. Some VOCs are dangerous to human health or cause harm to the environment. Anthropogenic VOCs are regulated by law, especially indoors, where concentrations are the highest. Most VOCs are not acutely toxic, but may have long-term chronic health effects
