Formaldehyde is a common toxic substance, which will do great harm to human health. Long-term exposure to formaldehyde can lead to headache, dizziness, cough, asthma and other symptoms, and even lead to cancer in severe cases. Therefore, we need to detect the formaldehyde content at home in time to protect the health of ourselves and our families.
Formaldehyde detection method
There are many methods to detect formaldehyde. Here are some common methods.
Air detection method
Air detection is a relatively simple and fast method. We can buy a formaldehyde detector and test it at home. The operation steps are as follows:
1. Turn on the formaldehyde detector and wait for preheating.
2. Put the test instrument in the center of the room and let it test automatically.
3. Wait a few minutes, and the testing instrument will show the formaldehyde content.
Reagent detection method
Reagent detection is an economical and simple method. We can buy a formaldehyde test kit and test it at home. The operation steps are as follows:
1. Open the formaldehyde detection kit and take out the reagent.
2. Put the reagent into the reagent tube and add a proper amount of air.
3. Wait a few minutes, the reagent will change color.
4. Determine the content of formaldehyde according to the degree of discoloration of the reagent.
Professional detection method
Professional detection method is more accurate and reliable. We can ask a professional testing organization for testing. The operation steps are as follows:
1. Find a professional testing organization and make an appointment for testing time.
2. Before the test, close all doors and windows to fully circulate the indoor air.
3. Testers will use professional instruments for testing, and the testing time usually ranges from several hours to one day.
4. After the test, the inspector will give a test report, which will indicate the content of formaldehyde.
Matters needing attention in formaldehyde detection
1. Close all doors and windows before the test to make the indoor air fully circulated.
Don't let anyone move in the room during the test, so as not to affect the test results.
3. The test result is only a reference value. If the formaldehyde content is found to be high, measures should be taken in time, such as ventilation and the use of formaldehyde scavengers.
4. When purchasing formaldehyde detection instruments or kits, you should choose the products of regular manufacturers to ensure the accuracy of the test results.
