Write in front:

With the development of science and technology, people's clothing, food, housing and transportation have undergone tremendous changes. However, the problem of air pollution is becoming increasingly serious. Living in the north, the author has been constantly attacked by "haze" weather since winter. For the safety of family and children, he has purchased an air purifier. The air quality cannot be observed in real time through the air cleaning equipment. Only continuous operation can monitor the indoor air quality in real time, which wastes both the power consumption and the service life of the filter element. If the mobile weather APP is used, the air quality parameters can only be used as a reference, and the accuracy rate is very low. So I had the idea of purchasing an air quality detector. In consideration of practicability, function and other aspects, I finally chose Radium2+. It is not only compact and easy to carry, with its own battery, but also highly practical and accurate. It is clear about indoor air quality and other parameters at a glance. In addition, it can also be connected with mobile phones for remote monitoring. Now let's have a detailed understanding and experience.

Unpacking:

Radon bean 2+, produced by Origin Life Technology, should be regarded as the third air detection product under the company. Compared with the previous two generations of products, Radon bean and Radon bean 2 have not changed much in appearance, but increased the detection of hundreds of harmful gases such as formaldehyde and phenol in air detection, which is more practical.

In terms of product packaging of Radium2+, a color printed carton is used for packaging. On the outermost floor is the box cover. The model and appearance of the product are marked in detail on the cover, and the parameters are introduced in detail in Chinese and English on the side, which is very comprehensive. It also supports the software download of iPhone and Android phones, and can realize the interconnection function with the help of the network. ‍

‍

Take off the box cover, you can see the whole package box, which is mainly white, without too much gorgeous decoration, and looks very simple and elegant. On the packaging box, the front and side appearance drawings of Radium Bean 2+are printed respectively, which are very vivid and of average size. Users can know its appearance without opening the packaging box. The internal space of the packing box is very compact, and you can see Radium bean 2+when you open the box. In order to ensure safe transportation, its surface is also covered with a layer of compressed foam, which plays a very good role in protection. ‍

‍

Radium2+is very simple in terms of accessories, only equipped with a blue USB power cord, and the relevant power plug is not equipped. However, in the era of the proliferation of intelligent devices, no one has a few charging heads. In addition, the related instructions are also indispensable. They detail the use methods and the overview of each detection mode. For first-time users, they are very helpful. ‍

Details and experience:

The appearance design of Radium2+still keeps the excellent characteristics of the previous two generations of products, and the appearance looks very dull and cute. The body is made of ABS engineering plastic, which is firm and durable. It feels very comfortable to touch with your hand. It feels good against your skin and does not leave fingerprints. Radium bean 2+has a body size of 106mm x 88mm and a weight of 285g. It is very light and can be placed without taking up too much space. Moreover, the color matching of the product is versatile, which can be well matched with different home environments and is very harmonious.

The front panel of the fuselage is round, and the center is a 2.6 inch, 320 * 240 TFT color screen. Although the pixel is not very high, the relevant parameters displayed are clear enough for daily use. The brand logo is also marked at the bottom of the screen, which has played a good publicity effect. At the edge of the panel, a ring of Tuhao gold decorative ring is designed to add a sense of luxury. Radium2+also has a built-in 2300mAh battery, which can be used continuously for 8 hours when fully charged. ‍

‍

The design of Radon 2+air detection air outlet is also very special. At the junction of the front panel and the rear shell of the fuselage, a circle of gap is designed, which is difficult to detect from the front, but also has a sense of suspension from the side. Its air inlet is designed at the rear of the fuselage, and is also equipped with a dust-proof net. The air flows into the monitor from the rear and finally comes out from the front air outlet. This simple cycle process completes the measurement of the current air quality, air temperature and humidity. In the middle of the air inlet is the charging port. After connecting the power cord, it looks like its small tail, which is very cute. ‍

There are two buttons on the top of the fuselage, namely the power button and the mode switch button. The keys are also made of plastic material and Tuhaojin color matching. The press feedback feeling of the keys is hard, and you can hear a strong sound of plastic texture when you press them, which makes them feel cheap. Long press of the power key can realize the operation of switching on and off, and short press of the mode key can realize the cycle switching and detection of CN composite index, AQICN, PM2.5 and other parameters. ‍

At the bottom of the fuselage, two very small legs are also designed, which can be placed on the desktop smoothly by taking advantage of the characteristics of the vertebral structure of the fuselage rear cover. However, when there is a large vibration, rolling still occurs. Another point is that the rear shell of the fuselage contacts the desktop for a long time, which is very easy to get dirty, and it is not easy to clean up. It is recommended that the authorities optimize it, Or it can be equipped with a bracket.

Radium2+can also be used without networking. However, in order for users to experience more powerful functions, they can also connect with mobile phones. As mentioned earlier, they can support both iPhone and Android phones. Internet control can be achieved by installing an APP software called "Kaiterra", and then operating according to the relevant connection setting steps.

Kaiterra's interface is very simple, and its functions are clear at a glance, which can be used quickly. The content displayed on the home page interface is the air quality of the current location, and it has also made a detailed column icon in hours. The trend of air quality is clear at a glance.

For other parameters, such as AQI. PM2.5, TVOC, temperature and humidity can all view the relevant columnar historical charts. In addition, you can add or delete the monitoring location of the city or define the location of the equipment through the setting menu, and you can also modify the temperature unit, language and AQI detection standard. The language supports simplified Chinese, traditional Chinese and English, and can be switched as required. AQI supports both Chinese and American standards. If the air is good according to Chinese AQI standards, then it is unqualified according to American AQI standards. It can be seen that the AQI standards of the two countries are quite different.

In the Radon 2+device setting menu, you can adjust the brightness of the screen, turn off or turn on PM2.5, TVOC, TVOC Index, weather and other displays, and view the update of firmware version. As for remote monitoring and other functions, they cannot be realized through actual measurement, and must be realized under the same network. ‍

The screen display content of Radium2+is also very simple. The default interface after startup is the CN composite index, which is a standard developed by Kaiterra and combines the measured values of PM2.5 and TVOC. When the composite index rises, it means that the level of pollution and potential health threats increase. When this index rises, it can be concluded that the air quality in the current environment is very poor, and ventilation or purification treatment is needed. ‍

AQI is the abbreviation of Air Quality Index, which is a dimensionless index to quantitatively describe air quality conditions. The larger the value, the higher the level and category, and the darker the color, the more serious the air pollution, the greater the harm to human health. AQI is a new air quality assessment standard issued by the state in March 2012. There are six pollutants monitored: sulfur dioxide, nitrogen dioxide, PM10, PM2.5, carbon monoxide and ozone. The data is updated every hour, and AQI presents the six pollutants with unified evaluation standards. In general, this value is high in haze weather, so try to avoid going out. ‍

PM2.5 refers to particles with aerodynamic equivalent diameter less than or equal to 2.5 microns in the atmosphere, also known as lung permeable particles, which sounds scary. Although PM2.5 is only a small component in the earth's atmosphere, it has an important impact on air quality and visibility. PM2.5 has a small particle size, is rich in a large number of toxic and harmful substances, and has a long residence time in the atmosphere and a long transport distance, so it has a greater impact on human health and atmospheric environmental quality.

‍

TVOC is one of the most serious indoor air quality pollution. How is TVOC defined? According to relevant literature, TVOC refers to the organic matter whose saturated vapor pressure exceeds 133.32 pa at room temperature. Its boiling point is 50 ℃ to 250 ℃. It can evaporate at room temperature and exists in the air. Its toxicity, irritation, carcinogenicity and special smell will affect the skin and mucous membrane, causing acute damage to human body.

TVOC mainly comes from outdoor, mainly from fuel combustion and transportation; while indoor TVOC mainly comes from combustion products such as coal and natural gas, smoke from smoking, heating and cooking, adhesives, coatings, paints, panels, wallpapers, etc. in building and decorative materials, furniture, household appliances, furniture, detergents and human body emissions. In general, when cooking at home or in newly decorated rooms, TVOC values are generally high. At this time, it is necessary to turn on the air purifier or take other purification measures to avoid affecting health over time. ‍

Radium bean 2+also supports real-time monitoring of particle quantity, temperature and humidity. The author also made an accuracy test on the "temperature", turned on the indoor air conditioner to set the temperature, observed the change of Radon 2+temperature display, and finally stabilized at the same temperature as that set by the air conditioner. It can be seen that the accuracy is still very high. ‍

After the mobile APP is connected to the Internet, the content displayed will be more abundant, which can show the weather conditions of today and the next three days, bringing more convenience to life. The user can also switch to night mode through the mode key. At this time, the screen will darken to save power. When the mode key is pressed again, it will exit. ‍

Experience summary:

Radium bean 2+not only has a small size, a cute shape, but also has practical functions. It can not only detect the CN composite index, AQI index, TVOC, PM2.5 and other air quality numerical tests, but also realize weather forecasting, smart home linkage, remote monitoring and other functions through networking. Although some functions are not yet available, there is a buffer stage for the launch of new products, I believe that the subsequent optimization and upgrading will be realized.

In these days, I found that I could not leave it any more. Previously, I used air purification by feeling, but now I have radium bean 2+by vision. When I saw the values rise, I would turn on air purification to purify the indoor air, which is accurate and fast. I feel relieved when I see the air indexes fall. Radium2+seems to have become a little helper in life. For newly decorated users, radium bean 2+can also be used to detect whether indoor formaldehyde and other harmful substances exceed the standard, and then take corresponding measures to purify or ventilate, so as to give more healthy care to their families.
