1. Applicable scenarios: home, hospital, swimming pool, disease control center, water plant laboratory, aquaculture industry2. Detectable range: 0-99903. IPX6 waterproof body, prevent a lot of water splash4. Powered by two button batteries (included)5. Can detect three types of impurities in water:- Calcium ions, magnesium ions and other soluble salts- Ammonium acetate, sodium sulfonate and other ionic organic substances- Heavy metal ions such as chromium, zinc, lead, and copper6. The water quality varies from country to country in different regions. The TDS test pen can accurately detect the TDS value of water, and can detect the purity of water before and after filtration, which reflects the filtration capacity of the water purifier. In general, the lower the TDS value, the less dissolved solids in the water and the purer the water quality.7. We cannot intuitively understand the purity of drinking water. Seemingly clear and transparent water may contain many impurities. The TDS value
