The AQM-101 is designed to measure HCHO concentration, air temperature and relative humidity with visible and audible alarms. This HCHO monitor is an ideal instrument for indoor air quality (IAQ) diagnosis and HVAC system performance verification.
FORMALDEHYDE (HCHO) is a gaseous component of the earth’s atmosphere. The concentration of HCHO in natural ambient air is about 0.03 ppm. Formaldehyde is found in a number of products. While most of these products contain a relatively low amount of the compound, others have a fairly strong concentration of formaldehyde. This is particularly true with products used in the course of scientific research and other professions where tissue is preserved in some manner. Formaldehyde exposure can lead to side effects that range from mild to life-threatening.
