Formaldehyde Concentration Meter

The formaldehyde concentration meter detects changes in the concentration of formaldehyde molecules in the air through electrochemical or semiconductor sensors and converts them into electrical signals to display numerical values. It is used to detect formaldehyde levels in indoor air, furniture materials, etc., and to determine whether they meet safety standards.
Selection
When selecting a formaldehyde concentration meter, it is important to consider whether its detection range covers common concentration values, as the response time affects detection efficiency, and the sensor lifespan determines the usage cycle. Additionally, adaptability to environmental temperature and humidity, calibration intervals, and portability are also factors to take into account.
