After the decoration of the new house, the formaldehyde that floats in the air makes many families anxious. Formaldehyde is a colorless gas with a pungent odor. Long term exposure may affect health, especially for pregnant women and children. At this point, formaldehyde detectors have become the 'health guardians' of our families. But many people buy detectors but use them inaccurately, even wasting money. Today, let's talk about how to use a formaldehyde detector and avoid stepping on it.
What is a formaldehyde detector used for?
Simply put, a formaldehyde detector is a tool used to measure the concentration of formaldehyde in the air at home. It can help us understand the release of formaldehyde in newly renovated houses or furniture, and determine whether it meets safety standards. However, it should be reminded that household testing equipment is mainly a daily monitoring tool and cannot replace the testing reports of professional institutions.
The environment preparation before use should be in place
Before testing, it is necessary to ensure that the space is sealed. Formaldehyde concentration detection focuses on the content in a fixed space, and if the air is well ventilated, the detection becomes meaningless. So before testing, it is necessary to close the doors and windows and enclose the space for at least 1 hour. At the same time, it is necessary to turn off devices such as air conditioning and air purifiers to avoid interfering with the detection results. Also make sure that there are no indoor activities that may affect the detection, such as smoking, spraying perfume, and using alcohol.
Calibration is key, don't ignore this step
Many people buy detectors and use them directly, which is a big mistake! Calibration must be performed before use, just like restarting a phone after prolonged use. Calibration should be carried out in a place with fresh air, such as outdoors or well ventilated windowsills. Place the detector there and wait for 5-10 minutes for it to 'calm down'. Once the values stabilize, proceed with calibration. Some detectors require long pressing a button for 3 seconds to complete calibration, which cannot be skipped.
Correct detection method, remember these details
After calibration is completed, place the detector in the area that needs to be tested, preferably using a bracket to place it upright, ensuring that all surfaces can come into contact with the air. During testing, it is important to avoid strong winds such as electric fans and air conditioners blowing directly towards the testing port, as this can affect accuracy. It is recommended to test for at least 20 minutes before seeing a stable reading.
Avoid interference sources when testing: perfume, alcohol, cigarettes, paint and other chemicals may affect the test results. At the same time, do not cover the detection port during testing, and do not blow air towards the detection port, otherwise it will interfere with the normal operation of the instrument.
These common misconceptions should be avoided
Don't use low-priced detectors as professional tools: Online 'detectors' priced at tens of yuan are often inaccurate and cannot be used to determine whether they exceed the standard. This type of product may only detect air and cannot accurately measure formaldehyde.
Don't think that the detector can replace professional testing: Home detectors are mainly used for daily monitoring, and the data may not be accurate enough. For the first test, it is recommended to find an institution with CMA qualification and issue a professional report. Afterwards, daily monitoring can be done using a household detector to compare data changes.
Do not use in humid environments: When the humidity exceeds 65% RH, the test results may be higher and affect accuracy.
Don't go uncalibrated for a long time: It's best to calibrate home testing equipment every once in a while to ensure accuracy.
Tips after use
After testing, remember to turn off the device and store it in a cool and dry place. If not used for a long time, it is recommended to remove the battery to avoid battery leakage and damage to the instrument. Do not place the detector in a place where it will be exposed to water, and do not subject it to severe vibration or impact.
Final reminder
Formaldehyde detector is a good helper for family health, but it is important to pay attention to the method when using it. Don't take the test results too absolute. If you find that the formaldehyde concentration is too high, don't panic and first check if there is a problem with the testing method. In addition to testing, the most important thing for newly renovated houses is to maintain good ventilation, which is an effective method for removing formaldehyde.
Remember, formaldehyde testing is not a one-time deal, but a process that requires continuous attention. Regular monitoring with a detector and ventilation through windows are necessary to make the home safer and healthier. If the test results do exceed the standard, then consider seeking professional institutions for treatment, which is both cost-effective and reassuring.
New home decoration is not easy, health is the most important thing. Mastering the correct detection methods, formaldehyde detection will no longer be a difficult problem, and our home will truly become a warm harbor.
