Chinese people like new things, get married, live in a new house, buy new household appliances and furniture; Wear new clothes for the New Year. But do you know that these furniture, coatings and daily necessities contain formaldehyde, an invisible killer. Formaldehyde was identified as a Class 1 carcinogen in 2006. In addition to carcinogenesis, the main hazards of formaldehyde are irritation, allergy, fetal malformation, memory disorder, etc.

Although many people know its hazards, they do not know the specific indoor conditions and the concentration standard of its hazards. Today, we bring an intelligent air detection hardware for the purpose of "protecting babies".

In fact, the function of this product is not to protect children, but to monitor the air quality at home in real time. Its small size allows you to carry it with you and measure where you go. Let's get to know this 720 Environment Treasure PLUS. Simple white paper box is used for packaging, and the brush design of the best gift for life is bold and unrestrained.

It is very thoughtful to remind that the first time you use it, you need to charge it first. If not, you will not test it under low power. The connection method is also clearly indicated. The profile shows that the color of Environment Treasure is shell white.

The internal package of 720 Environment Treasure is compact, the foam protects the product well, and the opening design at one end makes it easy to take out the product. It can be seen that the PLUS of Environment Treasure is a white design, and the official also presented a very cute film.

The 720 Environment Treasure is small in size, looks like a power pack, and weighs 175g Usually, it can be put into a bag or pocket for use as a portable power pack. However, there are not many highlights in this design, but there is an opening in the corner that can hang some lanyards or keys.

The side is inlaid with a strip of metal, which has a good texture, but the text pattern on it is not very obvious, which is followed by noise detection opening, Bluetooth connection indication, PM2.5 indication, formaldehyde detection indication and noise detection.

The shell is white engineering plastic, which needs to be considered in terms of dirt resistance and wear resistance. We hope that the official will provide a cloth bag or silicone cover to effectively protect the product and enrich the color of the product.

The side opening is used to collect the surrounding air. Since the machine has not been disassembled, it is unknown whether the opening on one side can form convection and whether the air to be measured can enter effectively. Besides, one of the functions of Environment Treasure is to detect temperature, but whether its heat dissipation capacity will affect its stability?

720 Environment Treasure PLUS adopts 5V 1A input, and the battery capacity is 3600mA.

In terms of keys, 720 Environment Treasure PLUS has a physical key for connection, and four indicators are placed on it to display the power, one Micro usb interface and one USB 2.0 interface. Because of its portability, the manufacturer designed it to be used as a power bank.

The first thing to get the 720 Environment Treasure PLUS is to charge it. As mentioned earlier, it is impossible to detect when the battery is low.

While charging, let's learn about the app of 720 Environment Treasure PLUS. It's very simple and clear. First, the guide interface introduces the applicable population of the product, new home decoration, smokers, people who need to test the indoor environment and those who want to live a high-quality life.

Then pair. First search and press the button of 720 Environment Treasure to connect, which is very fast.

The home page shows the recently measured comprehensive indicators. The upper test prompts the recent weather conditions according to the positioning, and then formaldehyde can be detected separately.

Net life includes life, mother and baby. It shares a lot of useful knowledge, and you can also put forward some questions about mother and baby in it. A group of enthusiastic people will help you answer them. It would be more perfect if the local environment was taken and complained.

What to do about the poor quality after the environmental monitoring? The APP can help you solve the problem (here is the advertisement). Tesco Mall includes a series of products such as air purifier, water purifier, mask, environmental treasure, formaldehyde cleaner, etc.

After charging for about 20 minutes, the test can be carried out. Return to the main interface, click the test button, and the 720 Environment Treasure PLUS will start to work in order. The test is carried out according to the process, including temperature, humidity, and noise, PM， Formaldehyde. The following figure shows the results of two tests in the same environment. It can be seen that there is a gap between PM and noise. Other aspects cannot be verified, but 720 Enviro has a large noise, so I think this test is not accurate. After the test, the data will be summarized and some useful tips will be given.

The following is a comparison with a 360 air safety master. It can be seen that only the humidity is the same. As for the temperature, the mercury thermometer in the home shows 24 ℃, so I suspect that during the charging and testing process, the 720 Environment Treasure PLUS heats up, causing errors in the testing, and the noise is partly caused by the noise emitted by the machine, But the most critical formaldehyde test is more accurate, and the test results are the same as those of home precision test paper.

After the comprehensive test, the formaldehyde content can also be tested separately. It can be seen that the amount of formaldehyde in the environment is stable at 0.12mg due to the lack of windows and ventilation, which is very harmful to sensitive people.

For this reason, the author has adopted two methods. The first method is to put a bag of activated carbon next to 720 Environment Treasure PLUS (the left figure), and it can be seen that it has little effect on formaldehyde. Therefore, the so-called bamboo charcoal, activated carbon purification of indoor formaldehyde is a long-term process, while the second method is to open a window during the detection process, and formaldehyde beeps down when cold air blows in.

In addition to the visible haze, people should also pay attention to the indoor hidden killer formaldehyde, especially mothers, infants and children. Although the appearance of 720 Environment Treasure PLUS is ordinary and other testing capabilities need to be considered, its formaldehyde testing capability is good. Compared with some ugly large-scale formaldehyde testing equipment, it can be said that the cost performance ratio is very good. We expect 720 Environment Treasure PLUS to be able to display through the internal screen in the future, reduce the noise, and believe that it will become a very good product.
