Simple Operation & Quick Results:Designed for easy plug-and-play use — just prepare two cups of water, insert the electrodes, power on, and observe the color change in 30 seconds. Clearly shows water purity differences between tap, filtered, and purified water.
Visual Water Quality Test:Uses electrolysis technology to make impurities visible. Different colors appear as metal ions react in water, helping you easily identify contamination and compare water quality levels at home or in class.
Home & Educational Use:Perfect for household water testing, science teaching, or classroom demonstrations. Great for helping students understand electrolysis, ions, and water composition while ensuring safe drinking water for your family.
Safe Design:Equipped with 4 detachable metal rods for stable performance and easy cleaning. Built-in anti-leak structure ensures safe operation and longer lifespan for repeated use.
Wide Application Range:Suitable for testing tap water, well water, filtered water, distilled water, aquarium water, and more. Compact and lightweight, ideal for home laboratories, schools, or portable water-quality testing anytime.
Safety Warning:Do not touch the electrodes or put fingers into the test water while the device is powered on. Keep out of reach of children. After use, unplug the device, wipe the electrodes dry with a soft cloth, and store in a dry place
