Happy with product ### ⭐⭐⭐⭐⭐ Review *by G***E on 13 July 2022* Users needs to underatnd diff between tds and total hardness .... i am water condtioner expert with patent granted for water conditioner technology. Tds means total dissolved salts ..simply it converts conductivity into tds .. and total hardness is amount of calcium and magnesium in water .... more tds does not mean water is hard it is just condctive .... more tds may be because of sodium and potassium.... example just add 1 tea spoon salt in water it will make it say from 100 ppm to 500 ppm but if check hardness using this kit .it would be same as before ...reason is addition of sodium does not make it hard but coductive .... thia kit is easy to use and very effective . ## Frequently Bought Together - AQUASOL Plastic Total Hardness 250 Test Kit, 5-500mg/L (Blue) - Konvio Neer Imported Tds Meter, Total Dissolved Solids Meter, Water Quality Tester, Ppm Tester For Water Testing - White - KONVIO NEER Total Ph Meter,TDS Meter and Ph Strip Combo, Full Water Testing Kit with Buffer Powder --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/600200098-aquasol-plastic-total-hardness-250-test-kit-5-500mg-l](https://www.desertcart.pt/products/600200098-aquasol-plastic-total-hardness-250-test-kit-5-500mg-l) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-18*
