What is the good thing about the formaldehyde detector of Jiabaoyu?

Formaldehyde detection has national standards that can be followed, 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.

The formaldehyde detector is used as follows:

1. Close doors and windows before formaldehyde detection and maintain normal daily life. Then, set up sampling points in the room, with diagonal or plum blossom distribution points, 1-3 points in the room below 50 square meters, 3-5 points in 50-100 square meters of cloth, and at least 5 points in more than 100 square meters, and the distribution points should avoid ventilation places such as doors and windows, and the distance from the wall is greater than 1 meter.

1. During the acceptance of civil construction projects, the concentration of indoor environmental pollutants in representative rooms should be sampled, and the number of sampling inspections shall not be less than 5%, and shall not be less than 3 rooms, and when the total number of rooms is less than 3, all should be tested.

2. During the acceptance of civil construction projects, if the indoor environmental pollutant concentration test of the model room is carried out and the test results are qualified, the number of sampling inspections shall be halved and shall not be less than 3.

3. During the acceptance of civil construction projects, the indoor environmental pollutant concentration detection point should be set according to the room area: when the room use area is less than 50m, 1 detection point shall be set up; The usable floor area of the room is 50100

m, set up 2 detection points; When the usable area of the room is more than 100 m, 3-5 detection points are set up.

4. When there are 2 or more detection points in the room, the average value of the detection results of each point should be taken as the detection value of the room.

5. During the acceptance of civil construction projects, the on-site detection point of environmental pollutant concentration should be not less than the height from the ground of the building from the inner wall. Detection points should be evenly spaced out and avoid ventilation ducts and vents. As long as you open the Jincheng formaldehyde detector, the formaldehyde reagent is ready, and the formaldehyde time is set to ten, the spectroscopic detection result will automatically read out the detection value on the LCD screen, and you can also get the temperature and humidity values and the results of formaldehyde exceeding the standard at the same time.

Through the built-in printer, the formaldehyde test results can be printed directly, which is convenient.

2. Precautions for using formaldehyde detector:

Before the test, the detection environment is sealed for 1 hour, and the formaldehyde is fully and evenly distributed in the environment;

Do not carry out activities that affect the test results, such as smoking and using gas stoves, during the closure process and testing process;

The testing site needs to be cleaned up, and residual paints, paints, plates, etc. cannot be stacked;

Do not use chemicals such as air fresheners, perfumes, alcohol, etc. during the closure process and during the testing process.

3. The formaldehyde standard is below the standard; Before the air treatment is carried out in the testing environment, please strictly follow the above methods to detect the formaldehyde content;

4. Please do not use ordinary dry batteries, so as not to burn the circuit of the machine; After the free rechargeable battery cannot be used, please purchase a rechargeable battery;

<> in general, formaldehyde detectors still have some effect, but they are generally extremely expensive, and they are not used a few times, and most of those cheap detectors are unreliable. Therefore, the average family is still not recommended to buy a formaldehyde detector, if you want to detect the formaldehyde concentration in the house, spend dozens of dollars to buy a formaldehyde self-test box to detect it, not only the most cheap, but also the test results are more accurate, which can effectively judge whether the indoor formaldehyde concentration exceeds the standard. If you are still not at ease, then ask a professional indoor environmental protection company to come to the test, which is definitely more effective than spending thousands of dollars to buy a formaldehyde detector.

Lekong Formaldehyde Detector, Lekong Formaldehyde Detector LKC-200 is a new household formaldehyde concentration detection instrument.

Formaldehyde detection boxes are also good or bad, generally look at the following points: 1It is necessary to choose a detailed manual, with both principles and instructions.

2.It is necessary to choose a pure water concentration with more perfect water purification equipment, and the measured results will be more accurate. 3.

To be mechanically filled. 4.It is better to add an anti-jamming agent.

5.Be sure to buy the glass bottles. 6.

The Mumei test is pretty good.

You can use the Qingyi formaldehyde self-test box to detect, and the selection of the test box generally depends on these three points:

1.It is best to add an anti-interference agent, because there are many impurities in the air, which can interfere with the test results and cause inaccurate results. The function of the anti-jamming agent is to eliminate the interference of these impurities. Therefore, it is necessary to choose a detection box with an anti-jamming agent.

2.Be sure to buy the glass bottles. Many small manufacturers use plastic bottles for testing liquid, because plastic bottles are cheap.

However, the plastic component will react with the test solution for a long time, which will have a negative impact on the test result. The glass bottle is much better, and it will not leak, but the cost is a little higher.

3.Mechanical filling. The test box is very precise, and it must be filled mechanically to achieve this accuracy.

4.Imported phenol reagent, RO grade purified water.

Formaldehyde detector category:

1.The use of probes for testing, on behalf of the instrument XP-308, 4160, PPM400, etc., is characterized by direct reading of data, easy to carry, the disadvantage is that it is greatly affected by temperature and humidity, needs to be corrected with standard gas, low daily maintenance costs, the probe is generally replaced in 1 year, and it takes thousands of yuan.

2.The use of spectrophotometry to analyze readings, there are Japanese Riken FP-30, domestic Ji size swan, the former uses finished tablets, the instrument is small in size, 15 to 30 minutes after sampling direct reading, the accuracy can be reached, the cost of maintenance is about 17 yuan tablets, and the machine does not need to be maintained at all. The relative operation of the little swan is more complicated, the steps required after 15 minutes of sampling are cumbersome, the accuracy can be achieved, the characteristics of this kind of instrument are also more prominent, the accuracy is high, the influence of the interference gas is small, and the temperature and humidity are compensated.

3. Handheld formaldehyde detector is a handheld instrument that can continuously measure formaldehyde. This product is suitable for environmental monitoring, industrial production, chemical industry and other places with formaldehyde.

4. The portable formaldehyde detector can be zeroed at the test site without the help of outdoor air. It is used in indoor formaldehyde gas detection in public places, indoor formaldehyde gas detection in civil buildings, and formaldehyde content detection in building materials.

Formaldehyde detector features:

It is not affected by extreme high temperature and humidity environment, and has a humidity compensation function. Formaldehyde readings are displayed in ppm or mg m units. One-button operation for fast sampling and fast recovery time.

The standard configuration includes a formaldehyde correction source (valid for six months) and the calibration procedure can be completed in a matter of seconds. Supplied with 10 phenol filters to exclude the influence of phenol on readings. Optional computer remote control software and adapter make the formaldehyde detector a wireless monitoring system.

Users can also choose to use a basic data processing device to print data in real time.

Detection method: direct measurement.

A single measurement where the sensor box is inserted into the host unit, and the host unit is inserted into the sensor box for a single 30-minute or 1-hour inspection in direct measurement mode (longer sampling times provide slightly better results).

Sampling measurements. The sensor box is used as a passive sampler and the detection results are read out by the host unit. The sensor itself can be used as a passive sampler. No fans and pumps required.

The changes in relative colorimetric absorbance that occur in the sensor are read by the host unit before and after sampling and converted to formaldehyde concentration.

Continuous measurement. The host unit is inserted into the sensor box for continuous long-term monitoring of the formaldehyde gas concentration. The host unit reads the absorbance change every 30 minutes and stores it, reading it continuously (or until the sensor reaches saturation).

Precautions for use:

1.The test water must be distilled, deionized, or purified.

2.The bubble absorption bottle should not be connected to the air inlet hole, otherwise it will cause back-sucking, damage the instrument, and lose the absorption solution.

3.All glassware should be cleaned with pickling solution, tap water, and distilled water in the chemical laboratory before being used for the first time.

4.After each test, the colored solution in the bottle should be absorbed by bubbles in time, and then cleaned with pickling solution, tap water, and distilled water.

Professional testing, the box with a tripod sampler is recommended! S5 and S6 models can be searched for indoor air detection instruments produced by Jincheng.

No matter what brand of formaldehyde detector is, we should understand its detection accuracy through multiple channels, because formaldehyde detection data directly affects our evaluation of indoor air quality.

In order to avoid the suspicion of advertising, it is indeed inconvenient to say the specific brand of formaldehyde detector here, just like the formaldehyde detector reported by CCTV news some time ago.

Look at it and compare it more, no matter what kind of formaldehyde detector, or that sentence, detection accuracy is very important.

The formaldehyde detector I use myself is very sensitive.

It is recommended to conduct on-site inspection.

Question 1: Is the indoor formaldehyde detector easy to use? You can find a dedicated inspector to conduct door-to-door testing, or you can go to the market to find a home testing instrument or test box.

If the test result shows that it exceeds the standard, then you have to think about removing formaldehyde, which should not only be formaldehyde but also benzene, and it is difficult to avoid formaldehyde when you have just decorated it.

Question 2: Has anyone used a formaldehyde detector and how does it work? I bought a Lekong formaldehyde detector, which is quite simple, and can be returned if you are not satisfied, with advanced laser sensing technology.

Question 3: Is the home formaldehyde detector useful? It's useful, you can test whether it exceeds the standard, but generally it will not exceed the standard except for just decoration.

Question 4: Is the household formaldehyde detector easy to use? Can I use it all the time? Yes, yes. As long as it doesn't break.

But isn't it a bit strange to test for formaldehyde at home if it's okay.

In the early stage of decoration, you can test more and then spray some herbal dialine at home to remove formaldehyde.

Read more about ventilation.

Question 5: Is the household formaldehyde detector easy to use The electronic formaldehyde detection equipment is not easy to use, and the error is very large.

Question 6: Is the household formaldehyde detector easy to use? Can I use it all the time It's pretty easy to use, I can use it all the time.

Hope it can help you, if your problem is solved, please click on it, thanks.

Question 7: Is the indoor formaldehyde detector easy to use Enjoy the indoor formaldehyde detector to directly read the formaldehyde concentration when turned on, the large screen LCD display, and the intelligent sound and light alarm reminder function of exceeding the standard. Let you know the air quality situation at home in real time, and monitor formaldehyde, TVOC, temperature and humidity in real time 24 hours a day.

Question 8: Is the household formaldehyde detector easy to use? Can you use it all the time Domestically produced household formaldehyde detection instruments use very cheap sensors, the detection accuracy is very low, and it is not as accurate as the formaldehyde self-test detection.

Question 9: Do you think the formaldehyde detector is useful? Of course, it worked, especially for those who have the elderly and children at home, I used the Lekong formaldehyde tester, which really scared me at first, and the excess was not generally serious, but fortunately it was found early or it would be miserable.

Question 10: Is the indoor formaldehyde detector easy to use? You can find a dedicated inspector to conduct door-to-door testing, or you can go to the market to find a home testing instrument or test box.

If the test result shows that it exceeds the standard, then you have to think about removing formaldehyde, which should not only be formaldehyde but also benzene, and it is difficult to avoid formaldehyde when you have just decorated it.
