Formaldehyde measuring instrument, and formaldehyde test box which is accurate

Several methods for detecting formaldehyde:

Formaldehyde self-test box, formaldehyde self-test box is a convenient and cheap method, but its accuracy is not high, and when it comes to the final color discrimination, different data will appear according to people's color difference.

Portable home detectors, which are easily affected by other odors, cause data bias and can only be used as reference data.

Formaldehyde testing companies and formaldehyde testing companies have professional testing instruments, and the data deviation is very small.

The formaldehyde test box is inaccurate, because the self-test box is a detection method, which cannot completely replace the standard test results.

The principle of formaldehyde self-test box is also to detect the formaldehyde content in the product through the color card, and the test results can only be used as a reference, because the test results are easily affected by factors such as air circulation, indoor temperature and humidity, resulting in a certain error in the test results.

Here's how to quickly remove formaldehyde from a newly renovated house:

1. The newly renovated house can be ventilated first, and it should be ventilated at least 4 times a day, and each time it should be more than half an hour.

2. You can also buy some spider plants, pothos and other leafy plants at home, these plants can not only play a beautiful role at home, but also help us to install formaldehyde absorption, purify the indoor air, we can put more spider plants at home, because spider plants can be called the king of polyoxymethylene in the plant world.

3. The most common method is to use activated carbon to remove formaldehyde, whether it is a refrigerator or furniture, you can use activated carbon to put around, activated carbon has a very good adsorption capacity, can absorb some toxic substances in the room, pay attention to regularly put activated carbon outside for sun exposure.

4. Photocatalyst formaldehyde removal is also a very effective method of false propaganda, photocatalyst is also a harmless substance, which can be used to decompose indoor formaldehyde and other toxic substances.

It's not accurate at all, and it's outrageously wrong, so you should not use this test box for testing, it's a complete waste of money.

It is relatively accurate, and the instruments generally used in the process of testing are relatively advanced, and the results of the inspection are generally fair.

Generally, the following methods are used to remove formaldehyde:

1.Open the window and put some plants that can absorb formaldehyde.

2.Open the doors of drawers, wardrobes, cabinets, etc., and put some long-term adsorption of Ye Guang mud, which can adsorb and decompose formaldehyde in the cabinet, and it can be used for 3 years better than activated carbon.

3.You can put a fan to enhance air convection, photocatalyst, photophyll and the like can decompose formaldehyde when it meets light, and it is used in industry to remove formaldehyde, and photophyll will be much better.

4.It is better to open windows in summer than in winter, and it is better to open windows during the day than at night (because the higher the temperature, the greater the humidity, the faster the formaldehyde will disperse).

The results are very accurate, and this method of measuring formaldehyde is also very scientific, and it is also liked by many people.

Relatively speaking, if it is operated and used correctly, the final result displayed is still relatively accurate. But be sure to pay attention to the method used.

The easiest way to detect formaldehyde at home is to use formaldehyde test boxes, but the detection may be affected by temperature, humidity and space size. After introducing how to measure indoor formaldehyde concentration, let's bring you some efficient methods for removing aldehyde.

1. Wise Stone.

It is a purification product favored by decoration families in recent years, compared with other formaldehyde removal products, its own pores are more, with the dual function of absorption and decomposition, and the speed of formaldehyde removal is also fast. Its unique decomposition function can save the time of drying, and it is more convenient to use, which can effectively control the formaldehyde problem for a long time. When choosing, it is important to note that it is a gray ore with an irregular shape and is not a round particle.

2. Wind fan.

The fan can play the role of "inducing air" to accelerate the discharge of the gas containing free formaldehyde in the room to the outdoors, this method is only useful for the house with poor ventilation, and has little effect on the house with good ventilation effect.

3. Plants.

Plants are the best products provided by nature to remove formaldehyde, and the more respected ones on the market are: pothos, spider plant, ivy, and aloe vera. These plants are a combination of beauty and talent, both to decorate the home and to purify the air.

Fourth, photocatalysts.

Photocatalyst, as the name suggests, is a catalyst mentioned in our junior high school chemistry, which decomposes formaldehyde into carbon dioxide and water through light, reduces the formaldehyde content in the room, and achieves the purpose of removing formaldehyde

Fifth, high temperature.

High temperature can promote the release of formaldehyde, reduce the total content of formaldehyde inside the material, and reduce the release of formaldehyde in the later stage.

Most of us are office workers, and time is very limited, so if you want to remove formaldehyde from the air as soon as possible, it is best to do it in a variety of ways at the same time.

In fact, to be honest, the overall effect of the kit to measure formaldehyde is not good, she is not particularly accurate, if you want to be accurate, you can buy a special formaldehyde measuring instrument, or find a professional to help you test.

Of course, the reagent and the detection of formaldehyde are accurate, and the corresponding kit is used to detect formaldehyde, which is targeted and specific, as long as the items you are testing contain formaldehyde.

The formaldehyde measurement of the kit is generally not accurate, and it is necessary to find a professional unit to measure.

As long as it doesn't expire, it's basically accurate, and this thing has been released for many years, and it's already very accurate, just like pH test strips, very accurate.

Formaldehyde detection box is accurate, but not accurate.

The formaldehyde self-test cassette is effective. The principle of the formaldehyde self-test box is generally to use chemical adsorbents to quickly adsorb formaldehyde components in the air. Then, through the color reaction, the formaldehyde content in the indoor air is roughly estimated by comparing the colorimetry.

It is characterized by convenience and speed. The disadvantage is that the values are not accurate enough and are susceptible to interference by factors such as temperature, humidity, air pressure, surface area of the detected liquid, and air velocity. If the formaldehyde content exceeds the standard severely, it can be detected with it.

If it is not too much, if it is, the formaldehyde self-test box may not be easy to detect.

How to use:

1. Before testing, close the doors and windows of the room to be tested for 2 hours. Pour all the liquid from the brown glass bottle into the plastic box.

2. Tighten the cap and shake it, and open the cap after the contents are completely dissolved.

3. Rotate the plastic box to be inspected indoors or at a height of 80 to 150 cm from the ground, and expose it for 40 minutes.

4. Pour the liquid in the colorless glass bottle completely into the plastic box.

5. Tighten the cap and hold it tightly with your hands, and shake it for 5 minutes while heating your body temperature.

6. Compare color with the colorimetric card, and read out the formaldehyde concentration value per cubic meter of air in the measured room (or furniture).

The formaldehyde test box is inaccurate.

Because the self-test box is a test method, it cannot completely replace the standard test results. The principle of the formaldehyde self-test box is also to detect the formaldehyde content in the product through the color card, and the test results can only be used as a reference.

Because the test formaldehyde detection box is to absorb formaldehyde through a specific liquid, the result is easily affected by air circulation, and then through the discoloration mechanism, the test result will be affected by factors such as temperature difference, light and viewing angle, resulting in a certain error in the test results.

Indoor formaldehyde removal

Opening windows for ventilation is the easiest way to remove formaldehyde, and it doesn't cost much, so be sure to open the windows often for ventilation after renovating your new home.

Plant adsorption, and secondly, we can also buy some plants to take home, such as spider plant, green dill, aloe vera and other green plants, which can not only beautify the environment, but also absorb formaldehyde and purify the air at the same time.

Activated carbon removes formaldehyde, activated carbon is still very effective in removing formaldehyde, mainly because activated carbon has a porous structure and has a very strong adsorption capacity. In addition, activated carbon has low cost and long life to remove formaldehyde, which is very suitable for formaldehyde removal.

Photocatalyst decomposition method, photocatalyst is a catalyst that decomposes harmful organic substances such as formaldehyde and toluene into harmless gases through the action of light to achieve the purpose of removing formaldehyde. If the photocatalyst is a harmless substance, the decomposition product is harmless, and it is a high-quality material for removing formaldehyde.
