## Summary description

BWT AQA test water hardness test kit (model 240011024) is a reagent set designed to determine water hardness. The kit provides chemical reagents for titration-based or colorimetric measurement of hardness levels, helping assess scale risk and inform water treatment decisions. Suitable for household and commercial water testing and maintenance of filtration systems.

## Long description

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.
