The increase in the demand for alcohol testers “fires†a number of offline and online merchants, and many buyers have responded with fake and shoddy products, and government regulators need to step up efforts to protect consumer interests.
According to the sources provided by the Xinhua News, the "alcohol tester" purchased online is not only inaccurate, but also very fake. Xin Xin Shi Bao reporter searched the Internet according to the website provided by Mr. Li and found that such products ranged in price from a few yuan to several thousand yuan, and the largest number was 50 yuan. The reporter contacted an alcohol tester merchant according to the website. One woman told the author that the instrument is now selling particularly hot, and the recent shipments have been more than in previous months. According to the woman's introduction, many drivers sometimes drink wine for hours. They don't know whether alcohol is completely volatile and can't drive on the road. If you buy an alcohol tester and test it on the road, you'll feel more comfortable. According to Mr. Chen who bought the tester, some people in Yinchuan have also promoted the alcohol tester. However, after the trials, the data was not accurate. Those who drank had no test and the sensitivity was not high.
The police reminded the driver that the special alcohol tester for traffic police was a police equipment that was ordered and issued by the relevant national authorities. After a special quality inspection, the sensitivity was very high. Alcohol testers currently on the market are mostly counterfeit goods, and are far from the traffic police testers. Some are even three products.
Drivers want to avoid being cheated, in addition to the government supervision departments to increase supervision, insisting that "drinking does not drive" is to avoid the "penalty" of the king.
Filter valves are responsible for controlling the filtration process, which removes impurities and particulate matter from the water. They can be further classified based on their control methods, such as manual, semi-automatic, or fully automatic.
Softening valves, on the other hand, are designed to remove hardness-causing minerals like calcium and magnesium from the water. They can be categorized based on the number of tanks controlled by a single valve, such as single tank or multi-tank systems.
Additionally, softening valves can be classified based on the automatic regeneration method used. This includes time-based regeneration, meter-based regeneration, or demand-initiated regeneration.
The flow direction of the regeneration liquid is another factor that determines the type of softening valve. It can be either downflow, upflow, or counter-current flow.
The control method of softening valves refers to how the valve is operated and controlled. It can be manual, semi-automatic, or fully automatic, depending on the level of automation and control desired.
In industrial applications, softening valves are commonly used for treating boiler feed water. The removal of hardness-causing minerals helps prevent scale formation and improves the efficiency and lifespan of the boiler.
