The customer should select the grade of ultrapure water equipment according to the actual water quality requirements. Ultra-pure water machines with tap water as the water source have two (two water quality) outlets, one is pure water, that is, three-stage water; the other is first-grade water, that is, ultra-pure water (strictly speaking, first-grade water) The resistance is greater than 10 megohms, while the resistance of ultrapure water is greater than 18 megohms. The above is the classification of the standard water used in national laboratories.
