There are many brands of formaldehyde detectors on the market, with different quality and price. Some low-priced formaldehyde detectors may have low accuracy and are easily affected by environmental factors such as temperature and humidity, resulting in errors. The use of formaldehyde detector also needs attention. Before use, the detector needs to be placed in the test environment to make it naturally balanced, and then tested. At the same time, we should pay attention to the detection range and time of the detector, and whether it is used according to the operation method of the manual.
Different countries and regions have different formaldehyde emission standards, so it is necessary to judge whether the test results meet the standards according to local standards. At the same time, the formaldehyde detector can only detect the concentration of formaldehyde in the air, but cannot detect the residual formaldehyde on the surface of objects. ?
To sum up, formaldehyde detector can detect formaldehyde, but we need to pay attention to its quality, usage and reference standard. If indoor air quality testing is needed, it is recommended to choose a professional testing institution or brand formaldehyde detector and follow the relevant operating specifications.
Matters needing attention in formaldehyde detection
1, safety protection: formaldehyde is a toxic and harmful gas, which is harmful to human health. Therefore, safety protection measures must be taken when detecting formaldehyde, such as wearing protective masks and gloves.
2. Accuracy of testing instruments: It is very important to choose formaldehyde testing instruments with high accuracy. Appropriate instruments should be selected according to the actual needs, testing sites and other factors. It is best to know the relevant specifications and technical parameters before buying, so as to avoid errors caused by improper purchase.
3. Selection of measurement location: When detecting formaldehyde, choose a suitable measurement location, generally in places where people stay for a long time or areas with high formaldehyde content, such as indoor decorated rooms and new cars.
4. Selection of measurement time: The formaldehyde content will change with the passage of time, so a suitable time should be selected when testing, usually after people stay for a long time.
5. Interpretation of test results: After formaldehyde testing, it is necessary to correctly interpret the test results and understand the meaning of relevant data, so as to correctly analyze and judge the test results.
