2 PCS Household Electrolyzer Test Tool for Water Purity Testing The device includes an electrolytic rod with positive and negative electrodes (one iron rod and one aluminum rod) to introduce an electric field into water. During electrolysis, iron ions (Fe³⁺) dissolve from the iron electrode and react with hydroxide ions (OH⁻) in water to form insoluble iron(III) hydroxide (Fe(OH)₃), which can adsorb and aggregate colloidal particles. Simultaneously, dissolved metal ions (e.g., manganese, potassium, cobalt) may undergo reduction and aggregation under electric current, leading to visible color changes in the water. Color indicators after electrolysis may suggest the presence of certain substances: - Yellow: May indicate dissolved acids, silicon compounds, organic minerals, molybdenum, fluoride, or other organic substances. - Green: May indicate arsenic, mercury, lead, copper, or sodium. - Blue: May indicate bacteria, viruses, organic phosphorus compounds (e.g., from fertilizers, detergents, pesticides). - Red: May indicate iron, rust, or bacteria. - White: May indicate lead, zinc, mercury, or inorganic salts. - Black: May indicate heavy metals such as zinc, lead, copper, chromium, manganese, or cadmium. Material: ABS, aluminum, iron Measuring range: 50 to –200 mg/L Rated voltage: 220 V, 50 Hz Intended use: Testing tap water and water from home filtration systems. Note: This tool indicates the presence of conductive substances in water but does not assess overall water safety, purity, or compliance with drinking water standards. Package includes: 1 x Electrolyzer body 2 x Aluminum rods 2 x Iron rods
