Dissolved oxygen analyzer measurement principle: the solubility of oxygen in water depends on temperature, pressure and dissolved salts in water. The sensing part of the dissolved oxygen analyzer is composed of gold electrode (cathode) and silver electrode (anode) and potassium chloride or potassium hydroxide electrolyte. Oxygen diffuses through the membrane into the electrolyte and the […]
