Brand：NANBEI Benchtop pH meter PHS-3C ModeA pH meter refers to an instrument that also replenishes the pH of a solution. The pH meter works on the principle of a galvanic battery. The electromotive force coaching technique between the two coatings of the galvanic battery is related to the protection of one's own properties and the protection of one's own properties. The concentration of hydrogen ions in the solution is related. There is a corresponding relationship between the electromotive force of the primary battery and the hydrogen ion concentration, and the negative logarithm of the hydrogen ion concentration is the pH value. The pH meter is a common analytical instrument widely used in agriculture, environmental protection and industry. l：PHS-3C
