Hanna Total Water Hardness Test Kit HI3812

Made in: Romania

Number of Tests: 100 tests per box

Type: Titration-based chemical test kit

It determines the total hardness concentration in two ranges: 0.0 to 30.0 mg/L and 0 to 300 mg/L. The HI3812 is supplied with all necessary reagents and equipment to perform the analysis.

What is Water Hardness?

Water hardness is defined as the capacity of water to subside soap. The ionic species causing precipitation are primarily calcium and magnesium. Other contributing ions include iron, zinc, and manganese. Controlling water hardness is essential to prevent scaling and clogging in water pipes.

How the HI3812 Test Kit Works

The HI 3812 tests hardness as mg/L (ppm) calcium carbonate, using an EDTA (ethylene-diamine-tetraacetic acid) titration method. For convenience, you can also use hardness test strips.
