What is hcho air quality?

The purpose of using an air quality detector is to understand the indoor air quality situation so that appropriate measures can be taken to improve indoor air quality. There are several factors to consider when selecting and using an air quality detector:

1. Choosing the right instrument: There are many different types of air quality testers available in the market, including Electrochemical gas sensors, light scattering sensors, and so on. It is crucial to choose the right instrument according to the needs and budget.

2. Placement of the tester: Place the tester at a height of about 1 meter above the ground, which is closer to the height of the pollutant release source, and make sure it is away from heating/cooling equipment such as air conditioners and heaters to avoid misleading results.

3. Regular calibration: It is very important to calibrate the air quality detector regularly to ensure its accuracy. Most manufacturers recommend annual or bi-annual calibration.

4. Interpretation of values: Users need to understand what the HCHO value means when the detector displays it. Generally, the lower the value, the lower the concentration of formaldehyde in the indoor air. However, the results of a test do not fully represent the entire indoor environment of the air quality, the need for multiple tests and comprehensive analysis.

5. Cooperate with other measures: In addition to the use of air quality detectors, users can also take some measures to reduce the concentration of formaldehyde indoors, such as the use of qualified furniture, ventilation, and air exchange.
