2 PCS Household Water Testing Tool – Electrolysis Water Quality Tester 1. This device uses electrolysis to detect the presence of impurities in water. It includes two electrodes—one made of iron and one of aluminum—connected to a power source. During operation, electrical current causes reactions that may produce visible color changes in the water, indicating the possible presence of certain dissolved substances. 2. Observed color changes during testing may suggest: - Yellow: Possible presence of dissolved acids, silicon compounds, fluoride, or organic matter - Green: Possible presence of arsenic, mercury, lead, copper, or sodium - Blue: Possible presence of bacteria, viruses, organic phosphorus (e.g., from fertilizers, detergents, or pesticides) - Red: Possible presence of iron, rust, or bacteria - White: Possible presence of lead, zinc, mercury, or inorganic salts - Black: Possible presence of heavy metals such as zinc, lead, copper, chromium, manganese, or cadmium 3. Housing material: ABS plastic; electrodes: aluminum and iron 4. Operating voltage: 220 V, 50 Hz 5. Intended use: For general household water observation and basic filtration system checks 6. Important notice: This tool is not a certified analytical instrument. It does not measure precise contaminant concentrations or confirm water safety. It is intended only for illustrative demonstration purposes and should not be used to assess compliance with drinking water standards. Package includes: 1 x Electrolyzer unit 2 x Aluminum rods 2 x Iron rods
