Total Hardness Chemical Test Kit
This chemical test kit measures total hardness as CaCO₃ by titration with EDTA. It includes all of the reagents and equipment necessary to perform approximately 100 tests.
- All required materials are included with the test kit, such as the sample beaker, plastic pipette, and reagent dropper bottles
- Pre-made reagents for ease of use
- All reagents marked with expiration date and lot number for traceability
- Manual titration performed with calmagite indicator
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.
: There is no need to buy a new kit when reagents are exhausted. Replacement for the reagents available for separate purchase (Hi3812-100).
