Review: Good Product, Displays the CACO3 hardness - Product is good and shows the hardness. I have tried it with low hardness and hardness upto 550PPM and it worked. Also has a limit that this can test hardness and clear in the box as well. One thing to keep in mind, the power shared in the bix may harden if you use wet hands or have moisture exposed as stated in the box. Review: Good - It works, the instructions are clear and easy to follow, but the cost seems a bit high. ## Features - Total hardness test kit - Hardness in water is caused by dissolved minerals and calcium and magnesium ions are usually present in significant concentration along with other divalent ions - Hardness creates scale deposit problem which lead to energy loss in different industrial systems, such as boiler, cooling system, cause scale formation in plumbing, heating appliances, and boilers ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B016QERCFO | | Best Sellers Rank | #10,308 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #3 in Plumbing Testing Equipment | | Customer Reviews | 4.3 4.3 out of 5 stars (298) | | Date First Available | 24 April 2022 | | Material type | Plastic | | Package Dimensions | 20.9 x 17.2 x 4.9 cm; 453.59 g | ## Images ![Total Hardness Test Kit (50-1000 mg/l) (500 Tests) - Image 1](https://m.media-amazon.com/images/I/51cdRqjOMlL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Product, Displays the CACO3 hardness *by G***R on 15 February 2025* Product is good and shows the hardness.

Very easy to use. The box is very handy and neatly packed. The only downside is experienced was the drops fall too quickly from T6 so it is difficult to measure accurately sometimes. From T2, drops fall in controlled manner but in T6 it just pours. ## Frequently Bought Together - AQUASOL Total Hardness Test Kit (50-1000 mg/l) (500 Tests) - KONVIO NEER Imported Total Dissolved Solids Meter, Water Quality Tester, PPM Tester For Household Drinking Water, Swimming Pools, Aquariums, Hydroponics and more(1) - AQUASOL Total Hardness Test Kit (2-100 mg/l) (250 Tests) --- ## 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.jp/products/484216172-total-hardness-test-kit-50-1000-mg-l-500-tests](https://www.desertcart.jp/products/484216172-total-hardness-test-kit-50-1000-mg-l-500-tests) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-01*
