Often referred to as playing, we all think of foreigners. After all, foreigners’ self-financing ability always looks a little bit stronger than we do. Now, a young man in Shenzhen has proved through his own actions: It is not only foreigners who play, but also people from our Chinese cities. Why do you say this way? First of all, the young man would play very much in his name. He took a stage name for himself as "a nutty brother." Combining a mobile phone with Comrade Luo, this is a rather emotional name. Do you understand what you are feeling? Anyway, Xiao Bian does not understand. Of course, this is not the point. The key point is that this man completed a feat in the near future: He collected 100% of the fog in all areas of Beijing, and made dust from the haze into a brick! This can be said to be a very remarkable thing, because it requires a lot of patience and a lot of time, but also have a certain amount of perseverance to be able to complete. After all, walking around the street with a suction device every day often leads people to think that they haven’t taken any medicine. Therefore, they still need a very strong psychological quality. In this process, the suction device he used was an industrial vacuum cleaner with a power of 1000 watts, a flow rate of 234 cubic meters per hour, and a filtration accuracy of 0.2 micron. It can take about 4 days after each charge, and in the 4 days, the amount of filtered air is about 62 people a day. That is to say, the air sucked by the vacuum cleaner during the 100 days used to make the tile is equivalent to about 1,550 people breathing in one day. This means that the 1550 people will inhale a brick every day! This is a very scary thing. In this regard, Xiao Bian does not want to express too much remarks. He only hopes that the people of the imperial metropolitan area will wear masks as far as possible in order to minimize the harm caused by this weather. Dissolved oxygen controller is a device used to monitor and control the dissolved oxygen content in water. Dissolved Oxygen Controllers require a Dissolved Oxygen Sensor to be connected. The sensor is used to measure the dissolved oxygen concentration in the water and transmit the data to the controller. The DO controller controls the dissolved oxygen content in the water body by adjusting other parameters according to the preset dissolved oxygen target range. The dissolved oxygen meter has 2 relays, which can set the closing value and breaking value, and 2-way 4-20mA current output, which can control the device more accurately.
It should be noted that the control of dissolved oxygen level involves many factors, including water body temperature, pressure, salinity and other water quality parameters. Daruifuno's dissolved oxygen controller supports compensation function. The dissolved oxygen controller also has RS485 output and time history recording function, and supports various installation methods.

The specific control method depends on the requirements of the application and the design of the system. A common control method is to control the dissolved oxygen content by adjusting the amount of aeration. Aeration is the process of increasing dissolved oxygen by passing air or oxygen through the water. The dissolved oxygen controller can automatically adjust the aeration amount or stirring intensity according to the dissolved oxygen data measured by the sensor to keep the dissolved oxygen concentration within a predetermined range.
