The value can reflect the cleanliness of water and can be applied to water quality testing in the fields of domestic water and hydroponics. (Total Dissolved Solids): Indicates how many milligrams of dissolved solids are dissolved in 1 liter of water. In general, the higher the value, the more lysate is contained in the water and the more unclean the water. Therefore, the size of the can be used as one of the basis for reflecting the cleanliness of the water.The commonly used testing equipment is a pen. Although it is inexpensive and easy to use, it cannot transmit data t
