Designed for 100 tests, it includes all necessary reagents and tools for accurate, on-site analysis, helping prevent scaling and maintain optimal water system performance. ## 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 | | Age Range Description | Adult | | Best Sellers Rank | #647,281 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #201 in Hardness Testing Equipment | | Brand | Hanna Instruments | | Brand Name | Hanna Instruments | | Customer Reviews | 4.3 out of 5 stars 15 Reviews | | Display Type | Analog | | Included Components | HI3812 test kit comes with 30 mL hardness buffer, 10 mL calmagite indicator, 120 mL EDTA solution, 20 mL plastic beaker with cap, 50 mL plastic beaker with cap and 1 mL syringe with tip.
