HI3812 Hardness test kit

Well water in Thailand is notoriously hard. Hard water can seriously  damage pool  equipment. In many cases a water softening system is required.

Calcium hardness must be actively managed—along with pH and total alkalinity—to keep water in proper chemical balance. Current industry standards call for maintaining calcium hardness in the ideal range of 200–400 ppm in pools and 150–250 ppm in spas.

The measure and subsequent control of water hardness is essential to prevent scaling and clogging in water pipes. and especially saltwater chlorinator cells.

The inexpensive HI 3812 titration test kit accurately tests the hardness .
Simple to use - no knowledge of chemistry is required Certain other ion species, such as iron, zinc and manganese, contribute to the overall water hardness.

Total Hardness range: 0.0-30.0 mg/L (ppm); 0-300 mg/L (ppm)

HI 3812 test kit comes with:
