In recent years, due to the serious air pollution problem, air purifier products continue to be popular. Although I live in the south, the air pollution problem will not be as serious as that in the north, but I also know that there will be many indoor air pollution sources, so I started the air purifier early. Usually, only when I see that the air quality index in the weather forecast exceeds the standard, or I feel that the room is relatively stuffy and the air is not circulating, I think of starting the air purifier. Now, with the Radium Bean 2+intelligent air quality detector, I can know the quality of the air at home at any time, so that I can make better use of the air purifier. It can be said that Radium2+intelligent air quality detector is the best partner of air purifier.

Radium bean 2+is packed in a white box similar to a cube. The outer layer of the box is also equipped with a paper box cover. The technical parameters, product information and product features of the machine are printed on the paper box cover in Chinese and English. The "Radium bean 2+" printed on the upper right corner of the front of the box cover is also particularly eye-catching. Before Radon 2+, Origin Life Technology launched Radon 2 and Radon 2 intelligent air quality detectors. Its quality has not only won the trust of embassies and Fortune 500 enterprises in many countries, but also is the first and only PM2.5 detector in the world to enter the Apple Store.

Radon 2+is a functional upgrade on the basis of the previous two generations of products. In addition to retaining all the functions of Radon 2, it also added hundreds of new compounds such as formaldehyde and benzene. This new function is very necessary for indoor air detection, especially for people who have just finished decorating their houses.

Take off the outer paper box cover. The packaging box of Radium2+is quite solid. Open the packaging box and fix the body with a paper die. The accompanying accessories include the product instruction manual and USB charging cable.

Compared with the appearance of the previous two generations of products, the shape and size of radium bean 2+are basically unchanged, but I personally think it is unnecessary, because its appearance design is more in line with the aesthetic standards of the public, and it is very simple and delicate on the whole. If you have to find something different, it is that the body color of Radium2+is changed from white with silver outer ring of Radium2+and Radium2+to white with gold outer ring, which adds a bit of luxury.

The shell of Radium Bean 2+is made of ABS plastic, and the workmanship is very good. It doesn't feel like a touch on the hand. Its body size is only 106mm x 88mm, and its weight is 285g. It is very compact, does not take up space, and is easy to place. From the side, the fuselage looks like a bell. In addition to the white main color and the gold outer ring decoration, it looks very cute.

The front of Radon 2+is equipped with a 2.6 inch LCD full-color screen. Its main advantages are small size, low energy consumption, zero radiation and no eye damage. However, there are also all color deviations and general display effects. Considering that we only use it to view some data, we don't make too high a requirement. After all, screens with good display effects consume more power. In order to better protect the screen, a transparent Alec panel is also covered on the front.

The tail of the fuselage is the annular air inlet of Radium2+, from which the air enters, passes through the laser sensor and TVOC sensor inside the fuselage for rapid detection and analysis, and displays the detection results on the screen in real time. In the middle of the annular air inlet is a USB charging interface. Radon 2+has a built-in 2300 mA lithium battery, which can last for about 8 hours when it is fully charged once. I think the usage time of this device is too short. Fortunately, it uses the USB charging mode. Connect the mobile power supply to charge it.

If there is an air inlet, there must be an air outlet. The air outlet of Radon 2+is ingeniously designed in front of the fuselage. Its panel and shell are not closely combined, but leave a small gap. Since the air inlet and air outlet are relatively small, there is no working noise after Radium2+is turned on.

Radon 2+is equipped with two mechanical keys on the top of the machine body, namely the power key and the mode key. The key cap is relatively small, so the press feeling is not very good. If you can change it to a touch key, it will be more powerful. By clicking the mode key, you can cycle through the interfaces of composite index, PM2.5, TVOC, particle quantity, weather query and night mode in sequence.

Radium2+is equipped with two fulcrums at the bottom of the fuselage. Although the fulcrums are not large, the machine is still quite stable when placed horizontally.

After understanding the exterior design and details of Radium2+, let's take a look at its system design. It starts up very fast, and the main interface silently displays the CN composite index TV. The index numbers on the screen are displayed in large font, so it is clear at a glance. In addition, the upper right corner of the screen shows the indoor temperature, the lower left corner shows the power and WiFi status, and the lower right corner shows the mode name of the current interface.

The CN composite index is a standard developed by Kaiterra, which combines the measurements of PM2.5 and TVOC. When the composite index rises, it means that the level of pollution and potential health threats increase. Every time I see the CN composite index rising, I know that the air purifier at home will be turned on. My home is close to the street. I also found that the CN composite index is relatively high every time when it is 7:00 p.m. or 8:00 p.m. I think this is because there are more traffic on the street at this stage, which leads to poor air quality.

AQI is the air pollution index, which is based on the ambient air quality standards and the impact of various pollutants on human health, ecology and environment, and simplifies the concentrations of several air pollutants routinely detected into a single conceptual index value form. It grades the air pollution degree and air quality status, and is suitable for representing the short-term air quality status and change trend of cities. Radon 2+provides two AQI reference indexes for China and the United States. After selecting US through mobile phone APP, the composite index will also show the reference index of the United States. I will not say which pollution index is more accurate, but I can only say that there is a big gap.

PM2.5 fine particle machine refers to particles with aerodynamic equivalent diameter less than or equal to 2.5 microns in the ambient air. It can be suspended in the air for a long time. The higher its concentration in the air, the more serious the air pollution. Compared with the coarser atmospheric particles, PM2.5 is small in size, large in area, strong in activity, easy to carry 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 environment quality.

TVOC refers to the organic matter whose saturated vapor pressure exceeds 133.32pa at room temperature. Its boiling point is between 50 ℃ and 250 ℃, and it can evaporate at room temperature. Its toxicity, irritation, carcinogenicity and special smell will affect skin and mucous membrane, and cause acute damage to human body. It is one of the three types of indoor air quality pollution that has a more serious impact. Using radium bean 2+for multiple tests, this index at home has always been very low, I can rest assured. The TVOC mode of Radium2+has two interfaces. The first interface displays the TVOC index, and the second refers to the TVOC concentration.

Radium2+can also detect the number of particles, and display the indoor temperature and humidity. After connecting to WIFI, the local weather forecast can also be displayed. In addition, it also has a more power saving night mode. After switching to this mode, the screen will automatically darken.

Kaiterra is the official APP designated by Radon 2+. It has two versions of Android and Apple IOS, but its voice air quality query function only supports Siri of Apple IOS.

To run Kaiterra for the first time, you need to add a new device. This step is very simple. Follow the wizard prompts step by step. It should be noted that Radon 2+only supports the 2.4GHz frequency band, while many routers now support the 2.4GHz and 5GHz frequency bands, so when connecting Radon 2+WiFi, remember to select the 2.4GHz frequency band.

Kaiterra's main interface is relatively friendly, simple and intuitive. Most areas of the screen display the comprehensive index information of local urban monitoring stations and the column chart of hourly index changes, while the lower part is the comprehensive index of real-time detection of Radium 2+. Enter the interface for viewing the real-time detection data of Radium2+, you can more intuitively understand its AQIPM2.5, TVOC, temperature and humidity detection data, and users can view it in minutes, hours or days. In the setting options, you can also choose China's or the United States' AQI standards. The gap between the two is quite large, which shows that the United States' AQI standards are more stringent.

Kaiterra can also adjust the screen brightness of Radium2+, and can also turn on or off the specified mode according to your own preferences. At present, Kaiterra is unable to realize remote monitoring of Radium2+, and the mobile phone must be in the same network environment with Radium2+to view various real-time data. In addition, the official claimed custom alarm reminder function is also not found in the current version of Kaiterra, and I believe it will be added later.

I personally think the monitoring data of Radon 2+is quite accurate when I experience it, because I also use the weather forecast app to check the local air quality index of the day every day, and find that the comprehensive indexes monitored by Radon 2+are not much different from them. When I turn on the air purifier, I find that the monitoring data of Radon 2+also begins to change, and various indexes have dropped a lot, This also means that the air purifier works. For many people who have just decorated their houses, they often check whether the formaldehyde, benzene, xylene, TVOC, particulate matter, etc. in the indoor air environment exceed the standard. I think this is radium bean 2+that can also be used.
