Compact and easy to use, it helps professionals quickly evaluate water softener efficiency, reduce soap consumption, and prevent scale buildup. Trusted by thousands with a 4.6-star rating, this kit is an essential tool for maintaining optimal water quality in both residential and industrial settings. ## Description Water hardness is caused almost entirely by calcium and magnesium ions. Other di- and trizalent metals have a similar effect, but usually are not present in high enough concentration in potable waters to cause problems. Hardness increases soap consumption in laundries and causes scale in boilers. Hardness test kits include the inexpensive Models 5-B and 5-EP designed for those needing quick checks on the efficiency of water softeners. More sophisticated test kits allow the determination of total hardness as well as calcium and magnesium (by difference). ## Features - Water hardness is caused almost entirely by calcium and magnesium ions - Hardness increases soap consumption - Hardness test kits include the inexpensive Models 5-B and 5-EP ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008FM7WLU | | ASIN | B008FM7WLU | | Batteries Included? | No | | Batteries Required? | No | | Customer Reviews | 4.6 4.6 out of 5 stars (1,881) | | Customer reviews | 4.6 4.6 out of 5 stars (1,881) | | Date First Available | 15 February 2015 | | Date First Available | 15 February 2015 | | Included components | Lab | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 254 g | | Item model number | 145300 | | Item model number | 145300 | | Manufacturer | HACH COMPANY | | Manufacturer | HACH COMPANY | | Package Dimensions | 12.7 x 6.91 x 6.6 cm; 254.01 g | | Package Dimensions | 12.7 x 6.91 x 6.6 cm; 254.01 g | | Part number | 145300 | ## Images ![Hach 145300 Total Hardness Test Kit, Model 5-b - Image 1](https://m.media-amazon.com/images/I/81yV7KboZvL.jpg) ## Questions & Answers **Q: Okay, what am I doing wrong. The water was blue, not pink when I added the microspoon of chemical, no drops added.** A: It means your water is soft already. If it was pink, then however many drops you add to turn it blue, thats how many grains hard your water is. Since you did not have to add any drops that means your water is 0 grains hard. **Q: What is the hardness range for this test kit? Thanks** A: You can always dilute your sample to extend the range. Dilute with soft water (distilled, clean rain water, or previously softened water). Just check that the soft water tests for zero hardness before using it. 1:1 dilution would double your range. 1:9 would extend the range by a factor of 10. A cheap drugstore syringe could be used for dilutions if you don't want to eyeball it. **Q: Does this kit come with the test tube and mixing bottle like the one from Hach?** A: Hach's part number 145300 does come with the measuring tube PN43800 and Glass Bottle PN 43900 **Q: Why would the color of soft water turn blue as soon as the indicator is added to the sample, without any additionof the titrant?** A: This happens normally, if the water is soft (zero grains of harness). The grains of hardness is the number of drops of titrant you have to add to get the water to turn blue. If you do not have to add any drops of titrant, then you have zero grains! ## Frequently Bought Together - Hach Total Hardness Test Kit, Model 5-B, Water Analysis Kit for Drop Count Titration, with 2 Reagents, Measuring Tube, Square Bottle & Measuring Scoop, 145300 - HoneForest Water Quality Tester, Accurate and Reliable, TDS Meter, EC Meter & Temperature Meter 3 in 1, 0-9990ppm, Ideal Water Test Meter for Drinking Water, Aquariums, etc. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/271343783-hach-145300-total-hardness-test-kit-model-5-b](https://www.desertcart.ae/products/271343783-hach-145300-total-hardness-test-kit-model-5-b) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-06-18*
