Total Hardness Chemical Test Kit

Total Hardness Chemical Test Kit

Total Hardness Chemical Test Kit is a chemical test kit that measures total hardness as CaCO₃ by titration with EDTA. The kit is supplied complete with all of the reagents and equipment necessary to perform approximately 100 tests.

FEATURES AT-A-GLANCE

• Complete setup
  • All required materials are included with the test kit, such as the sample beaker, plastic pipette, and reagent dropper bottles.

• High resolution
  • Readings from 0.0 to 30.0 mg/L are determined to 0.3 mg/L resolution.
  • Readings from 0 to 300 mg/L are determined to 3 mg/L resolution.

SIGNIFICANCE OF USE

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.
