Measurement of Available Chlorine in Electrolyzed Water Using Electrical Conductivity

Strongly acidic and strongly alkaline electrolyzed water (SAcEW, SAlEW) are readily prepared from water containing NaCl by direct current electrolysis. SAcEW has a strong bactericidal activity due to the available chlorine (AC) concentration. We developed a device for measuring electrical conductivity in SAcEW instead of real measurement of AC concentration. The electrical conductivity in SAcEW was significantly correlated with the AC concentration.
