On the side of the packing box are some information about the model, size, weight, measurement error, measurement range, measurement temperature, battery capacity and manufacturer of millet water quality TDS detection pen.
The back of the box is printed with the structure introduction and use method of some millet water quality TDS detection pens. In fact, this is a brief instruction manual of the detection pen. No other instructions are attached to the box.
The packaging box of Xiaomi TDS water quality detection pen is opened by pulling, and there is a layer of light blue inner lining packaging inside. The detection pen is placed in the paper inner lining packaging, and it is firmly fixed to avoid the occurrence of back and forth shaking damage during transportation.
In addition to the millet water quality TDS detection pen, there is a small warranty card in the packaging box. There is no separate instruction manual, which is all of it.
·Appearance·
Millet TDS water quality detection pen adopts pure white color matching, and the pen body adopts IPX6 waterproof body with no hole design, which can effectively avoid water infiltration during use.
The size of Xiaomi water quality TDS detection pen is 150 * 16 * 16mm, and the weight is 27.4g. It is only the size of one carbon pen, which is very convenient to carry.
There is a key and a display screen on the front of the detection pen, which are waterproof designed to prevent system failure caused by accidental splashing and water seepage. If the pen is not used for two minutes, it will automatically shut down, extending the use time.
The cap of the detection pen adopts a translucent frosted design. The pen head is divided into an external leakage temperature sensor and a high-precision anti-corrosion metal titanium TDS probe.
The top of the detection pen is also detachable. In fact, it is a battery compartment. The detection pen has two AG13 button batteries inside, which is convenient for users to replace independently.
·Using·
Having said so much, let's test it in practice. Four kinds of water sources are selected here, one is tap water, one is plain water (tap water boiled), one is bottled purified water, and one is barreled water (currently used). From the front, can you tell the name of the water source? I look at the same water except boiled water (with a small amount of scale on the surface).
Before the test, let's first make a simple understanding of the division of water quality. Generally, we believe that the lower the TDS value, the better the water quality. The TDS value of drinking water ≤ 1000mg/L is qualified. However, when the TDS value is higher than 300, scale will occur.
Now we start the test operation. The test method is very simple. Turn on the switch, and then put in the millet water quality TDS detector pen, and wait until the indicator is stable.
First of all, we tested the tap water directly from the water pipe at home. The TDS value tested was 344ppm, which has reached a level of slightly more scaling. This result is actually expected, because scale always occurs on the wall of the kettle at home before.
Will the boiled tap water change greatly? Facts have proved that the DTS value of plain water is 327ppm. Compared with tap water, it is basically unchanged, or it is slightly more impurities. This is something I did not expect. Do you still believe that tap water is safe to boil? In fact, it is no different from you directly and tap water. It can only be said that it has an additional layer of psychological effect.
Through the above tests of tap water and boiled water, I once thought whether the pen was broken. Then I changed a bottle of pure water of a brand just opened and tested it. The DTS value tested was 2ppm, which just proved the accuracy of the above two groups of data.
Finally, let's test the quality of the barreled water I am drinking now. Because I have not drunk tap water for many years, this value is my most concern. After testing, the DTS value of the barreled water is 139ppm, and the purity is indeed much higher than that of tap water, which makes me feel very happy.
Finally, we can have a more intuitive understanding of the comprehensive test results in the figure above. Of course, it's useless for you to see it, because it's our water quality. If you want to know about the water quality in your home, you should get a millet TDS pen and go home to test it yourself.
·Summary·
With the appearance of Xiaomi TDS water quality detection pen, you can get a more intuitive understanding of the water quality in your home at only 39 yuan. A test before drinking will make the healthy water quality clear at a glance. Especially for people like me, who live in a highly polluted environment and mostly rely on barreled spring water for drinking water, I can learn the purity of barreled water quality through the millet water quality TDS detection pen, so as not to be replaced by others' tap water. The barreled water is good now, and I look forward to a better barreled water source. In fact, it is the right way to improve the purity of our tap water. Now the tap water is really getting undrinkable.
