This professional water electrolyzer is a portable visual water quality testing instrument for labs, beauty salons, cosmetic R&D and household water purification demonstration. Adopting stable 6V DC constant current circuit and corrosion-resistant metal electrode rods, it generates visible sediment and color changes within 30–60 seconds to intuitively reflect dissolved minerals, heavy metal ions and TDS levels in tap water, distilled water or cosmetic raw material aqueous solutions.

Built with robust insulated ABS housing, the compact handheld design supports 110V/220V dual voltage to fit global markets including Ghana and other African regions. Electrodes are detachable for effortless rinsing and residue removal after each test, avoiding cross-contamination of different water samples. No complex calibration required; operators only need to submerge probes into 100–150ml liquid to start testing instantly.

Widely applied for salon hair care formula inspection, cosmetic lab raw water screening, school chemistry teaching and water purifier sales display. Safe, low-cost and repeatable, it delivers intuitive visual data to help formulators adjust pH and aqueous ingredient purity for hair dyes, masks and skincare emulsions.
