Today, Xiaomi held a media conference in Beijing. In addition to the new Xiaomi TV that everyone knows and the new Xiaomi tablet that everyone guessed wrong, Xiaomi also unexpectedly released the Xiaomi water purifier and TDS detection pen. Now let's follow the release time and take a look at these new products.

Xiaomi TDS detection pen

The first is the Xiaomi TDS detection pen as a gift for guests at the opening. The packaging of the machine is also a typical millet style (the mobile phone tablet has a kraft paper box, and other small accessories are all packed in pure white).

There is only one millet logo on the front, product specifications on the side, and very detailed product introduction on the back.

After opening the package, in addition to the San Bao certificate, it is the pen body.

Fully white polished body, with a translucent cap on the head.

The middle upper position is a simple LCD screen, which is only used to display TDS readings.

The pen head is the three metal contacts of the detection sensor.

At the end is the battery compartment printed with millet logo, which is powered by two button batteries.

The author conducted the test in the on-site bathroom, submerged 2/3 of the pen cap with the water sample to be tested, and stirred to remove the bubbles adsorbed on the pen head. The reading is stable in about 3 seconds, in ppm.

The TDS reading of tap water in this area of Beijing is about 170, which is not ideal (For reference, the reading of tap water in the toilets of Shenzhen office building is about 70ppm, while that of Ipoh barreled water is about 1ppm).

The full name of TDS is total soluble solids, that is, how many milligrams of soluble solids are dissolved in water. The unit is mg/L, or ppm, which is common but difficult to understand.

In fact, it is not used to test how good the water quality is, but to test how bad the water quality is. Because TDS does not include soluble salts, organic matter, and insoluble particles that can pass through the filter. However, if even a simple indicator such as TDS is failed, the water quality will certainly not be very good.

Xiaomi TV 2s

Then came the Xiaomi TV 2s, which occupied the main space in the press conference. As for why it is not Xiaomi TV 3, the main reason is that its appearance has hardly changed except for the backplane material and thickness.

The front bottom and base are not different from Xiaomi TV 2.

The body layout is very similar to that of Xiaomi TV 2. The vertically placed interfaces include two USB interfaces (one is USB3.0) and two HDMI interfaces.

The horizontally placed interfaces include the third HDMI interface, AV tricolor cable, network cable interface, audio output and other rarely used interfaces.

The fuselage panel is really thin, and has caught up with mobile phones. On the left is the S6 edge with a cover, and on the right is the Xiaomi Note.

The outer edge of the screen is metal wrapped, and the front is a black anodized frame. The screen edge still has a black edge of a certain width.

This time, the back plate is also replaced with the anodized aluminum process commonly used in mobile phones, which is much higher than the standard.

The miniaturized power connector made by twice injection molding is much smaller than the plug of millet patch panel on both sides.

There was also the dismantling of the TV on site. The whole circuit board of the TV is equipped with a 4-core A17 architecture MStar 6A928 CPU, Mali-T760 MP4 GPU, 2G memory+8G eMMC 5.0 flash memory.

Broadcom's BCM43569 wireless chip, 2.4/5GHz dual band wifi, 802.11ac dual antenna, Bluetooth and other modules are all on a separate circuit board.

8-speaker unit for AV version.

Color representation

In indoor lighting, the color performance, visual angle and fineness of the screen are also really good.

In the darkroom used for contrast testing, the default placement order is Sharp on the left, Xiaomi TV 2s in the middle, and Sony on the right. The test uses a macbook (below the figure above). After the video signal of the machine is transferred from one to three, it is respectively connected to three televisions.

The first is the dark field performance. The Sony Dafa (far right) of this model leaks light impressively, while Philips (far left) performs slightly better. Even considering the brightness difference of the upper backlight panel, the dark field performance of the Xiaomi TV 2s is really exaggerated (Sony on the right has the smallest maximum brightness).

Decoding capability comparison

Sharp has been criticized for its lack of special decoding processing. Even the 4K panel is still drunk when encountering the situation of "tiny+white characters on red background". Sony's performance of this model is similar to that of Xiaomi, and it is also the second flying Sharp model. However, whether Xiaomi's independent decoding scheme has the same significant improvement in other cases remains to be evaluated later.

The above is the color performance of the three TVs under the default brightness. You can see that Sony's brightness on the far right is much lower, but its actual appearance is actually the most comfortable. This requires the manufacturer to have enough confidence and the fans to have enough faith, because it is not conducive to the manufacturer to sell the machine in the store (under the light of the store, the machine with higher brightness will be more attractive).

Turn the Sony on the right to the highest brightness, as shown above.

Turn Sony's brightness to the highest, and the middle Xiaomi TV 2s brightness to the lowest, as shown above.

Millet water purifier

The shape of Xiaomi water purifier is similar to that of Xiaomi air purifier. They are all rounded rectangular cylinders, However, the water purifier is shorter and covers a smaller area. However, in terms of weight Pick it up It is heavier than air purifier.

The logo is below the front of the water purifier, and the working indicator is above.

Inside the accessory box are six faucet adapters of different specifications, and a multi size wrench for disassembly is also included.

There are no fixed clips on the upper cover. After taking it up, you can see the four filter columns of the machine.

There are detailed instructions, four filter elements, wifi and setting status indicators, and two buttons on the far right.

Inside the upper cover are the precautions and connection instructions for the phone.

Put down the machine, except for the logo, there are only four thick silicone feet.

The back is the nameplate of the machine, and the rated power is 96W.

Above the nameplate on the back is the power line and pipe outlet, and on the left is the thick pipe jointly sealed by water inlet and outlet, as well as the filter waste pipe and power line.

The water inlet and outlet are designed on the touch tap, which can leave a pipe position. The two buttons above can choose to directly come from the incoming water or the filtered water.

The waste water pipe is relatively thin, and there are two suction cups on it, which can facilitate the user to fix it to a suitable position. The detail design is very considerate.

Inside the machine are four columnar filter elements of different thickness, marked with serial number and name, and detailed specifications on the back.

Disassembly

There is also disassembly of water purifier on site.
