Hanna Total Water Hardness Test Kit HI3812 – Accurate Titration-Based Hardness Measurement
The Hanna HI3812 Total Water Hardness Test Kit is a precision titration-based chemical kit designed for reliable determination of total water hardness. Made in Romania, each kit provides 100 tests per box and comes complete with all necessary reagents and equipment to perform accurate water hardness analysis.
Water hardness is a measure of calcium, magnesium, and other ions such as iron, zinc, and manganese in water. Monitoring and controlling water hardness is essential to prevent scaling, clogging, and inefficiency in water systems.
The HI3812 kit determines hardness as mg/L (ppm) of calcium carbonate using an EDTA titration method. It is suitable for two measurement ranges: 0.0–30.0 mg/L for low hardness and 0–300 mg/L for higher concentrations, offering both precision and versatility.
