How to buy formaldehyde boxes? Which is more reliable?

It is recommended to purchase SGS-certified boxes directly. The most authoritative in the industry.

Formaldehyde boxes can be purchased on a treasure. The accuracy of the data of the box and detector for the convenient detection of formaldehyde is very poor, so it is not recommended to use it. The following picture is the test report of the Shenzhen Consumer Association on the formaldehyde box and handheld formaldehyde detector:

The highest error reached 228%, so which way should indoor formaldehyde be chosen?

CMA agency testing.

The state acknowledges that the report has the force of law and that the data is accurate and reliable, and is in the range of 300 yuan.

Formaldehyde removal company.

Compared with the accuracy of the CMA agency, the data is also credible, and when choosing a formaldehyde removal company, you should pay attention to see whether the other party's testing instrument has a CMA report, ** at 100 yuan.

The formaldehyde self-test box can only detect whether your home exceeds the formaldehyde standard, and can not accurately know the specific concentration of indoor formaldehyde. Generally speaking, the free formaldehyde contained in the household does not exceed m3, and exceeding this standard will threaten the health of the human body, especially the elderly, children, pregnant women and other susceptible people with low immunity. The formaldehyde self-test box can only detect whether your home exceeds the formaldehyde standard, and can not accurately know the specific concentration of indoor formaldehyde, and another point is that not all formaldehyde self-test boxes are standard, only through professional testing instruments to detect formaldehyde pollution in the home, is a more correct and scientific method.

Generally speaking, the free formaldehyde contained in the household does not exceed m3, and exceeding this standard will threaten the health of the human body, especially the elderly and children, pregnant women and other people with low immunity.

The cheapest is the test kit that you bought online.

Electronic detector bought online.

Find a professional institution for testing.

If it is just a random test, use the first two, and the accuracy is low. If you want to be accurate and healthy with your family, it is recommended to find a professional company for testing.

The formaldehyde detection box is accurate. The formaldehyde detection box is accurate, but not accurate, and cannot replace the standard detection, but it can give a general idea of the degree of indoor formaldehyde pollution. Formaldehyde self-test is imprecise in the specific value of the measurement, therefore, it is not an absolutely accurate detection, but a relatively accurate detection within a certain range of values.

The formaldehyde self-test box cannot completely replace the standard test, it is a convenient detection method to understand the degree of indoor air pollution.

How to use the formaldehyde detection box. 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 to read out the formaldehyde concentration value per cubic meter of air in the measured room or furniture.

Formaldehyde detection has national standards to follow, the detection principle is actually very simple, the most commonly used in the laboratory is also particularly suitable for measuring indoor formaldehyde is the phenol reagent method, the conditional will use chromatography, the instrument is more expensive than the cost of detection.

In 2019, CCTV also reported that most of the detectors on the market are inaccurate or have a large error, and even the detection of many exceeding the standard is not exceeded, formaldehyde is still very harmful, life is only once, how important and happy health is, and how sympathetic it is to see so many water drops.

I will share what I have learned with you, I hope it will be helpful to you, and you can make a discernment.

First, the electrochemical method of direct reading of the instrument, can achieve real-time reading, but many of the low-end sensors used are easy to fail due to environmental impact (to be honest, there is still a lot of room for improvement in domestic sensors), so that the detection results and the actual deviation is large, dozens of hundreds of such instrument sensors are not formaldehyde sensors at all, known as "air anemometer", this kind of instrument does not have tens of thousands of dollars don't want to measure indoor formaldehyde, indoor formaldehyde is relatively small if it exceeds the standard, and the sensitivity requirements for this kind of detector are particularly high;

The second is the formaldehyde kit, the detection principle is based on the national standard method phenol reagent chromogenic method, and the detection is relatively reliable in the first category (except for those in tens of thousands may be better), but the national standard law stipulates that 10 liters of air need to be collected quantitatively using a sampler, and the self-test box only stipulates: stand for 30 minutes.

How much of the volume of air reacts with the absorbent in these 30 minutes? This point is unpredictable, it may be that the indoor air circulation velocity is high and absorbs more, and the Brownian motion absorbs more quickly, on the contrary, the detection is not scientific, the randomness is too high, and it is best not to use it;

The third is a new generation: convenient pump-suction air formaldehyde detector, why is it convenient, because the professional testing company also uses the pump-suction type, compared with the traditional structure is more complex and professional, ordinary consumers will not operate, and the convenient pump-suction type on the market, optimized structure, easy to operate, although the process is the same, but it is indeed a lot simpler, completely according to the national standard detection method, the configuration of the pump-type sampler, users can collect a fixed volume of 10 liters of air by themselves, and then according to the national standard method phenol reagent chromogenic method detection, It makes up for the shortcomings of the formaldehyde kit.

After decoration, there will be a strong pungent smell, because the decoration materials emit harmful substances such as formaldehyde, benzene, toluene, xylene, ammonia, TVOC and so on. These harmful substances are particularly harmful to the human body, and long-term exposure can cause serious effects on human health and even endanger lives.

Just renovated, you can do a test of indoor air pollution after all the furniture is installed. At present, the air pollution rate of newly renovated houses in China exceeds the standard rate of more than 80%, if it is seriously exceeded, it is recommended to find a professional formaldehyde treatment agency to do indoor air pollution control.

At present, the most advanced third-generation treatment technology for indoor air pollution control in the domestic market: air catalyst, which uses nano-scale titanium dioxide as a catalyst for oxidative decomposition reaction, which not only solves the problem of poor effect of photocatalyst in the case of insufficient light, but also has a permanent effect. It has gradually replaced photocatalysts and become the most advanced air pollution control technology in the Chinese market.

Indoor air pollution testing should be entrusted to a professional testing company, and at the same time, professional testing instruments should be selected to obtain the test results through scientific testing steps.

It is not recommended to use a simple hand-held detector or test box. The error of these two methods is large, which will lead to the deviation of the detection results and cause the wrong way to choose formaldehyde treatment. This affects the health of the family.

Professional indoor air pollution detection instruments can detect: formaldehyde, benzene, toluene, xylene, ammonia, TVOC. Accurate to two decimal places.

The formaldehyde detection in Shenyang is calculated according to the detection point.

Taking Shenyang Jiajing Technology as an example, the testing equipment synchronized by the Quality Supervision Bureau is used, and the CMA test report is issued after being reviewed by the national inspection department. The fee for a testing point is 68 yuan, and 1-2 detection points are generally selected below 100 square meters, which means that only more than 100 can obtain six kinds of pollution data, which is affordable and accurate, and can also issue a test report to provide a reasonable solution. When choosing an indoor environmental protection company, you must choose a qualified and guaranteed company.

The formaldehyde detection box is a semi-quantitative and portable formaldehyde detection method developed according to the principle of "phenol reagent colorimetric method" in the national standard. It is more suitable for indoor formaldehyde pollution source detection, and is not very suitable for indoor space detection.

When purchasing, pay attention to R&D institutions, manufacturers, etc.

The kind of small box formaldehyde detection is basically the same. It is dissolved in chemicals by air, and then if there is formaldehyde, it will produce a certain amount of discoloration, and the sensitivity and accuracy are average, but it is probably okay to test one.

If the formaldehyde detection box for a few dollars is not very accurate, it is best to find a monitoring agency, absorb liquid sampling, and the spectrophotometer analysis is more accurate.

It's all about the same, 1, take activated carbon adsorption and then have to use the sun to dry it.

2. Take the tea leaves, take the coffee beans to suck the taste.

3. What green plants to buy, Tiger Piran, Aloe Vera, Cactus, these Buy a little more 4, Open the windows for ventilation, but open the weather, don't open it on rainy days.

5. Open the wardrobe, the desk, and the drawers.

If you have enough money, you can find someone from a special company to do it, or buy some Huankang nano aldehyde enzyme to treat it.

It's all the same, it's all the same.

The main thing is governance.

1. It is to open the window for ventilation for a long time (this effect is the best).

2. Air purifier (the power should be sufficient, or buy a few more, or it will be useless).

3. Green plants, spider plants, pothos, etc. (the number can not be less) 4. Find a professional company in addition to formaldehyde (pay attention to the company's qualifications).

5. Buy some herbs for dialin treatment. (herbal).

At present, there are many methods used for formaldehyde pollution detection, formaldehyde self-test boxes, household formaldehyde detectors, and entrusted formaldehyde testing institutions.

Among them: Qingyi formaldehyde self-test box: convenient and affordable, high precision, chemical method, relatively accurate.

Household formaldehyde detector: detect formaldehyde content at any time, more timely and convenient, and avoid being fooled. The disadvantage is that the accuracy of most domestic household formaldehyde detectors is not high, and attention should be paid to distinguishing the detection accuracy when choosing.

Not long ago, the formaldehyde detector reported by CCTV News Network said that the accuracy is very high, and it looks very good, you can take a look at the news yourself.

Entrust formaldehyde testing institutions: pay attention to identify whether it has CMA testing qualifications, if it is a formal testing unit, the data is relatively accurate, and avoid choosing the kind of unit that both detects and governs for testing, so as to avoid being deceived and deceived.

Detect it with a formaldehyde detection box, the detection principle of the formaldehyde detection box: formaldehyde in the air reacts with phenol reagents to form azine, which is oxidized into blue-green compounds by ** iron ions in an acidic solution, and is quantified according to the color shade and colorimetry. It is recommended to use the Maya blue formaldehyde detection box to detect it, and the test box is generally based on these three points:

1.It is better to add an anti-jamming agent. 2.

Be sure to buy the glass bottles. 3.Mechanical filling.
