Hanna HI3812 Offers

A titration-based chemical test kit that determines the total hardness concentration in two ranges: 0.0 to 30.0 mg/L and 0 to 300 mg/L. It is supplied complete with everything needed to perform approximately 100 tests.

Features

• All required materials are included with the test kit, such as the sample beaker, plastic pipette, and reagent dropper bottles
• High resolution
• Replacement reagents available, there is no need to buy a new kit when reagents are exhausted

Applications

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.
