Designed for 100 tests, it includes all necessary reagents and tools, enabling professionals to prevent scaling and maintain optimal water quality with ease. ## Description Water hardness has traditionally been defined as the capacity of water to precipitate soap. The ionic species in the water causing the precipitation was later found to be primarily calcium and magnesium. In the present, therefore, water hardness is actually a quantitative measure of these ions in the water sample. It is also now known that certain other ion species, such as iron, zinc and manganese, contribute to the overall water hardness. The measure and subsequent control of water hardness is essential to prevent scaling and clogging in water pipes. The HI 3812 test kit tests the hardness level as milligram per liter (ppm) calcium carbonate, via an EDTA (ethylene-diamine-tetraacetic acid) titration. The HI 3812 test kit tests the hardness level as milligram per liter (ppm) calcium carbonate is determined by an EDTA (ethylene-diamine-tetraacetic acid) titration. HI 3812 test kit comes with 30mL hardness buffer, 10mL calmagite indicator, 120mL EDTA solution, 20mL plastic beaker with cap, 50mL plastic beaker with cap and 1mL syringe with tip. ## Features - HI 3812 test kit comes with 30mL hardness buffer, 10mL calmagite indicator, 120mL EDTA solution, 20mL plastic beaker with cap, 50mL plastic beaker with cap and 1mL syringe with tip - Kit for 100 tests - Range: 0.0-30.0 milligram per liter (ppm), 0-300 milligram per liter (ppm) - Smallest Increment: 0.3 milligram per liter [0-30 milligram per liter range], 3 milligram per liter [0-300 milligram per liter range] - Chemical method: EDTA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0085WWPLW | | Age Range Description | Adult | | Best Sellers Rank | #313,814 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #81 in Hardness Testing Equipment | | Brand Name | Hanna Instruments | | Customer Reviews | 4.3 4.3 out of 5 stars (15) | | Display Type | Analog | | Manufacturer | Hanna Instruments | | Manufacturer Part Number | HI3812 | | Model Number | HI3812 | | Software Update Supported to Date | unknown | | Unit Count | 1 Count | ## Product Details - **Age Range (Description):** Adult - **Brand:** Hanna Instruments - **Display Type:** Analog - **Manufacturer:** Hanna Instruments - **Unit Count:** 1 Count ## Images ![Hanna Instruments HI3812 Single Parameter Hardness Test Kit, For 100 Tests - Image 1](https://m.media-amazon.com/images/I/31VVvEc2o4L.jpg) ![Hanna Instruments HI3812 Single Parameter Hardness Test Kit, For 100 Tests - Image 2](https://m.media-amazon.com/images/I/51rJiP0Y7cL.jpg) --- ## 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.no/products/11931792-hanna-instruments-hi3812-single-parameter-hardness-test-kit-for-100](https://www.desertcart.no/products/11931792-hanna-instruments-hi3812-single-parameter-hardness-test-kit-for-100) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-26*
