Water hardness test kit BWT AQA test 240011024 — reagent set for measuring water hardness

The BWT AQA test 240011024 water hardness test kit is a reagent set designed to determine the concentration of calcium and magnesium ions in tap and well water. The kit supplies the chemical reagents required for titration-based or colorimetric measurements, enabling users to assess water hardness and evaluate scale formation risk for domestic and small commercial systems. It supports informed decisions for water treatment, descaling and maintenance of filtration and softening devices.

Advantages

This reagent set is formulated for reliable detection of hardness levels and is compatible with standard titration and colorimetric procedures. The kit simplifies on-site testing with straightforward reagents and clear end-point indication, delivering consistent results for routine monitoring. Its composition is intended to be stable under normal storage conditions, reducing the need for frequent reagent replacement.

Suitable for

• Testing tap water and well water hardness in homes
• Regular monitoring of water used in boilers, kettles and household appliances
• Maintenance checks for water softeners and filtration systems
• Small commercial settings where hardness measurement informs scale control

Key specifications

• Reagent set for titration and colorimetric hardness measurement
• Measures concentration of divalent cations contributing to hardness (calcium, magnesium)
• Suitable for routine on-site testing
• Stable formulation for normal storage and handling
• Intended for household and small commercial applications

How to use

Collect a representative water sample and follow the titration or colorimetric procedure provided with the kit. Add the specified reagent drops or measured volumes to the sample, mix as instructed and observe the color change or titration end point to determine hardness value. Compare the result with common hardness scale units (e.g., mmol/L, °dH or ppm CaCO3) according to the kit instructions. Ensure glassware and containers are clean to avoid contamination and follow any safety guidance included with the reagents.

Usage recommendations

Store reagents in a cool, dry place away from direct sunlight and extreme temperatures. Replace reagents if discoloration or deterioration is observed. When interpreting results, consider testing multiple samples at different times to confirm typical hardness levels, and consult water treatment specifications to select appropriate softening or descaling measures.
