When I learned that the 720 Environment Treasure Plus trial was successful, I was very excited! Thanks again to Lei Feng.com for his great love for an ordinary little friend under the haze!

After receiving 720 Environment Treasure Plus, I measured my home environment with joy, and my mood fell to the bottom again! In the face of this model, formaldehyde in the air PM2.5、 The advanced instrument for accurate measurement of the noise of the thermometer and hygrometer has many feelings. This feeling is like the feeling of the pilot staring at the radar in the battle between the two armies at the front. The feeling of seeing the flash on the screen and not seeing it is extremely complicated.

When I was young, the sky in my home was blue. I never heard of the word PM2.5. Later I learned that its Chinese translation was: "serving the people in the fog"; Ten years ago, the song "Deep Breathe" in Yuquan sang like this: "Take a deep breath~~close your eyes, the world has the most fresh oxygen!...", and then take a deep breath 10 years later, you will completely close your eyes and play... Is this the legendary pain of breathing

When I looked up at the sky again, I had already changed my face, and the once blue sky became a memory fragment. Think about what we have done and what our society has done to this home! After watching the program "Xiaosong's Tales", I felt very much the same about one of the proposals for haze control. Gao Xiaosong's suggestion is to encourage everyone to plant trees, encourage the influential leaders in China to plant more trees. The more trees you plant, the more land you own. It is more meaningful than real estate speculation!

Although I am not a politician who cares about the country and the people, I also have the feeling of family and country to do my duty. I think I'm not the only one who said a lot about improving air quality that has nothing to do with 720 Environment Treasure Plus. Many people will have their own feelings about the current air conditions. It is also important to leave complex issues to the decision-makers. It is also important to do what is within our power to protect the environment.

First, briefly introduce the functions of 720 Environment Treasure Plus:

It can accurately measure the formaldehyde content, PM2.5 concentration, temperature, humidity and noise in the air within half a minute. Compared with the chemical test paper, 720Plus Environment Treasure has no pollution to the environment, can be recycled, and the measurement error is very small, with high accuracy; With the 720 Environment Treasure Plus, you can easily measure whether the formaldehyde content after the house is decorated exceeds the standard, and whether the purification effect of the air purifier is as magical as advertised. At the same time, this 720 Environment Treasure Plus is super portable and can be carried when traveling. It is an essential artifact for you to travel at home and measure the environment! What's more, it can also charge your mobile phone!

   Unpacking

▲ The package of 720 Environment Treasure Plus is different from that of other products. There is no product appearance drawing or too many performance parameters. Only a few bold words are printed on the box: "The best gift"! This is indeed a unique gift. What is more important than giving health

▲ There is an important prompt on the back of the packing box: charge up before use, and turn on the preheating function for 12 hours according to the instructions. The reason for this is not explained in the manual, which makes consumers confused. However, the above clearly indicates that if the instructions are followed, there will be uncertainty. In order to give full play to the functions of this product, I restrained my curiosity, and did it after 12 hours of warming up.

If you can't explain a phenomenon, find a reason to persuade yourself to accept it. First of all, the 720 Environment Treasure Plus has the function of a power bank. In order to play a good charge and discharge function, it is really necessary to conduct a full charge and discharge when using it for the first time; Secondly, after the formaldehyde measurement sensor is debugged and delivered from the factory, it is inevitable that many sundries and unknown gases will enter during transportation. In order to completely release the gas so as not to affect the measurement accuracy.

▲ A clear black and white color package, a charging data cable, a manual, and a sticker printed with bear patterns are quietly placed in the treasure box

Why is this product called 720 Environment Treasure Plus? I didn't care when I thought it was a product name at the beginning of use. However, the name of each product is intended to highlight its features, and it seems that it has grasped the true meaning after use. The one-dimensional plane is 360 °, and there is 720 ° in a three-dimensional space. 720 in 720 Environment Treasure means that every environment around you can be monitored freely. Treasure is a magic weapon for monitoring and a treasure for charging.

▲ 720 Environment Treasure Plus has two USB interfaces on one side, one physical switch/mode button and four power indicators;

As a power bank, you can plug the data cable into the USB port when charging mobile phones and other devices. 3600mAh can only supply power to the 720 Environment Bank Plus. It can also be a creative way to charge mobile phones that is truly energy-saving, efficient and environmentally friendly.

The small port is the interface for charging 720 Environment Treasure Plus. The four power indicator lights below the button indicate the remaining power during charging and discharging; It is used when the power button is on key and 720 Environment Treasure Plus is activated.

During the first trial, press this key quickly for 5 times. When the formaldehyde indicator light is green, Environment Treasure will be activated. It can be used after standing in clean air for 12 hours.

▲ The depression at the upper left corner is the air inlet. After being inhaled, the air passes through formaldehyde PM2.5、 After the temperature, humidity and noise sensors are monitored, they are discharged through the air outlet on the other side ▲ 720 Environment Treasure Plus exhaust outlet (side vent)

▲ There are five LED indicators on the other side, namely: working status indicator, Bluetooth connection indicator, PM monitoring status indicator, formaldehyde monitoring indicator, and alarm indicator; Various indicators will be explained during the use experience.

The 720 Environment Treasure Plus pasted by Little Bear is only the size of the palm of the hand, and the 175g weight is very convenient to carry.

II. Use Experience

▲ The mobile phone downloads 720 Environment Treasure, and the software is upgraded to 720 Environment Review after a period of time. The sharing function of the monitored pictures is added, which is very practical. The air quality released from the software or the weather station is very conservative. Some measuring stations are also different from their own geographical locations. With the measurement sharing function, more people can understand the real air quality.

The software is very, very simple to use. However, it must be activated according to the instructions before use. Otherwise, the measurement result may be inaccurate. The problem here is that after the software is upgraded, the device will be prompted to activate. In order to ensure the accuracy of the measurement results, the 12 hour activation is still selected. I don't know whether this will happen every time I upgrade. I hope there will be suggestions in the software help when I upgrade later.

▲ When measuring in a closed room for one day, the blue indicator light of Bluetooth is on after connecting the mobile phone to Bluetooth, and the pairing is successful. Click the Start Measurement button of the software to prompt comprehensive measurement/formaldehyde measurement;

Comprehensive measurement includes: formaldehyde PM2.5、 Temperature, humidity and noise measurement are real-time measurement;

Formaldehyde measurement: measure the change of formaldehyde content within ten minutes and analyze the content change trend with a curve (suitable for the measurement of air purifier and ventilation)

▲ Click the comprehensive measurement and start the measurement after the equipment warms up for a few seconds. The first measurement is temperature, humidity and noise measurement, and then PM2.5 and formaldehyde content are displayed successively. The equipment has noise during measurement, so in order to accurately measure the noise, PM2.5 content, formaldehyde value, noise, temperature and humidity will be measured separately. Since sensor monitoring takes time, the measurement will have a delay of several seconds, which is within the acceptable range.

The data displayed on the top of the software are official air data and outdoor data. As shown in the figure above, the outdoor PM67 air quality is good, the indoor PM2.5 is 17, the air quality is excellent, and the formaldehyde content within 0.1mg is the standard value. If it is higher than this value, the Environment Protection Plus will alarm.

After the test, there will be a prompt for the measurement results. When the air quality is normal, the software will prompt the use of 3M air purifier, water purifier and other products. A software is simple and easy to use, and the embedded advertisement is so natural, which is why you can't find the monitor on 720 Environment Treasure Plus~

▲ Formaldehyde detection is a dynamic detection process of its content within 10 minutes. The change of formaldehyde content is identified by curve, and the maximum value and ideal value will be indicated after 10 minutes of measurement. The formaldehyde removal effect of the air purifier can be identified through curve changes, and whether to replace the filter screen can be determined.

▲ 720 environmental review software can share the indoor air at home, the purification effect of air purifier, outdoor air quality, and the air monitored in public places to a third-party social platform such as WeChat, and share the most authentic air monitoring data with friends and more people concerned about air quality.

Comprehensive detection of the air in the house after decoration: formaldehyde will volatilize from the floor and furniture of the newly decorated house for 3-15 years. When the formaldehyde content exceeds 0.1mg, the human body will suffer from discomfort, poor breathing, asthma and other symptoms. If the pregnant woman is in the room with excessive formaldehyde content for a long time, it will cause great harm to the fetus in the abdomen, and there will be deformed children and leukemia children.

Through 720 Environment Treasure Plus monitoring, the conclusion is that the way to quickly reduce the indoor formaldehyde content is to open windows for ventilation. However, it is unrealistic to open windows for a long time in northern winter, so it is necessary to equip an air purifier at home. The 720 Environment Treasure Plus can not only monitor the purification effect of the air purifier, but also monitor the air purifier after a period of use to determine whether the air filter screen needs to be replaced.

The following is the detection effect when the window is not opened:

▲ The indoor PM2.5 content is 45, and the PM2.5 value detected by the radium bean air quality detector is 57, which is very close. Formaldehyde content is generally 0.08mg, and the Radium bean air quality detector has no formaldehyde detection function;

▲ After opening the window and ventilating for 2 minutes, 720 Enviro Plus measured that PM2.5 increased from 45 to 61, and the formaldehyde content decreased from 0.08 mg to 0.06 mg. It can be seen that window opening ventilation is an effective way to quickly remove formaldehyde!

▲ Monitor the formaldehyde removal, PM2.5 absorption and noise of Greenway air purifier through 720 Environment Treasure Plus. After monitoring, the conclusion is that the Greenway air purifier is a trustworthy air purifier.

Detection of Greenway air purifier: when the window is opened for ventilation in the living room, the formaldehyde content will be reduced from 0.08mg to 0.06, and then the formaldehyde concentration in the ventilation will be maintained at about 0.06mg. The formaldehyde content in the bedroom is up to 0.13mg, exceeding the standard value of 0.1mg due to the large number of households;

▲ After exceeding the specified range of formaldehyde, 720 Environment Treasure Plus turns on the alarm tone function, and the indicator turns red!

When the purifier is opened for about 3 minutes, the PM2.5 content will reach 24 and the formaldehyde content will reach 0.03mg. It can be seen that the purification effect of Greenway air purifier is very obvious.

Test effect of study: formaldehyde content is 0.05mg, PM2.5 value is 39, and the air purified by adding air purifier is excellent.

The air quality of the bedroom bed after monitoring and purification also reached a good value

Comparison of San720 Environment Treasure Plus and Radium Bean Air Quality Monitor

In terms of accuracy, both of them use sensors with high accuracy, which is undoubtedly seen from the detection results;

Different points:

720 Environment Treasure Plus looks like a power pack, while radium beans look like peas in the battle between plants and zombies;

Same points: PM2.5, temperature and humidity in the air can be measured;

720 Environment Treasure Plus Advantages:

Formaldehyde, PM2.5 content, temperature, humidity and noise can be monitored, and the results can be shared through Bluetooth connection;

Radium bean intelligent air quality detector:

Only PM2.5, PM10, temperature and humidity in the air can be monitored, not formaldehyde and noise. With screen display, intuitive, wifi communicates with mobile phones, and data is measured and displayed in real time

▲ 720 Environment Treasure for monitoring the purification effect of air purifier

When monitoring the Greenway air purifier, the real-time detection effect of radium bean is good, but only PM2.5 can be monitored

Purifier monitoring data

▲ Data change curve of purifier except PM2.5

According to the monitoring of PM2.5, the number of indoor PM2.5 particles decreased significantly in the first 200 minutes and 600-1000 minutes of the operation of the air purifier, while the PM2.5 content increased from 30 to about 60 in the standby period of the air purifier, indicating that the air purifier has a significant effect on absorbing PM2.5.

▲ The work of air purifier is the change curve of ambient temperature and humidity

The advantage is that the measurement results are displayed in real time through the display screen, while the 720 Environment Treasure Plus can only be displayed through the mobile phone. At the same time, Radium can send the monitoring data email to the customer for analysis.

720 Environment Treasure Plus is more suitable for comprehensive monitoring data and dynamic display of formaldehyde content changes.

In terms of portability, 720 Environment Treasure Plus is rectangular and easy to carry, and can charge mobile phones and other products at the same time. One machine for multiple purposes. Both have advantages.

▲ 720 Demonstration of measuring formaldehyde content in living room

Through the monitoring of 720 Environment Treasure Plus, the conclusions are as follows:

1. Ventilation by opening windows is an effective way to quickly reduce indoor formaldehyde content;

2. Opening the window can quickly remove formaldehyde, but the side effect is that the PM2.5 content increases close to the outdoor value, which is not the result we want. The air purifier can effectively reduce the indoor PM2.5 value

To sum up, the indoor formaldehyde content can be rapidly reduced by opening windows. When used together with air purifier, it can not only effectively absorb PM2.5 particles brought by opening windows, but also remove formaldehyde slowly released.

Summary:

720 Environment Treasure Plus can check the content of harmful gases such as formaldehyde, PM2.5, temperature, humidity and noise contained in the surrounding environment. It is a very portable and comprehensive air quality monitoring equipment. Easy to use app and fast and accurate measurement are the incomparable advantages of this detector over chemical test paper.

However, there are still shortcomings in the United States and China. For example, the change of formaldehyde content can only be displayed in curve form, and the PM2.5 value, temperature, humidity and noise value can only be displayed in breakpoint data. Fortunately, after the software is upgraded, it can be viewed through historical data. It is hoped that the optimization will continue in the future, and the display screen will be used more widely. The above is the evaluation experience of 720 Environment Treasure Plus. This is a very useful and practical product. Thank you very much for the trial experience provided by Lei Feng.com. Thank you for watching!
