The HI38033 is a chemical test kit that measures total hardness as CaCO3 by titration with EDTA. The HI38033 is supplied complete with all of the reagents and equipment necessary to perform approximately 100 tests.
Complete setup
All required materials are included with the test kit, such as the sample beaker, plastic pipette, and reagent bottles.
High resolution
Readings from 0 to 30 gpg are determined to 1 gpg resolution.
Replacement reagents available
There is no need to buy a new kit when reagents are exhausted. The HI38033-100 reagent set can be ordered to replace the reagents supplied with the kit. This reagent set comes with 1 (30 mL) dropper bottle of buffer solution, 1 (10 mL) dropper bottle of Calmagite indicator, and 2 (75 mL) bottles of HI38033-0 EDTA solution.
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. Thus, water hardness is actually a quantitative measure of these ions in the water. 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
