This experiment was conducted to study how to monitor water quality by measuring pH, acidity - alkalinity, hardness, chloride by means of a Mohr. And measuring the conductivity of distilled water and raw water, the results showed that the pH of distilled water and tap water were 8.59,7.24 and 7.98, respectively acidity is equal to 4 mg / l CaCO3,. 16 mg / l CaCO3 and 8 mg / l CaCO3 respectively, which is pH 8 mg / l CaCO3,116 mg / l CaCO3 and 112 mg / l CaCO3, respectively. Hardness equivalent to 70.50 mg / l CaCO3,138.18 mg / l CaCO3 and 124.08 mg / l CaCO3, respectively, the chloride content of 22.72 mg Cl, 90.88 mg Cl and 198.80 mg Cl, respectively, and the conductivity of 7.75 "μs. / cm ", 411" μs / cm "and 248" μs / cm ", respectively, making it possible to compare the differences in water quality from various sources. Contributions to the management of water before the water used in food processing.
