Water hardness test kit BWT Test Kit (model 1002000122) for measuring water hardness levels

The BWT Test Kit for measuring water hardness levels is a compact set designed for on-site determination of calcium and magnesium-related hardness. The kit contains reagents and simple tools that enable household users and service technicians to check water hardness quickly and reliably before installing or servicing water softeners, filters or other treatment equipment. The test kit supports routine diagnostics of water quality and helps confirm whether water hardness is within the expected range for a given application.

Advantages

This water hardness test kit offers straightforward operation with visual results and comes with the reagents necessary to perform multiple measurements. The compact, portable design allows use at the installation site or at home, reducing the need to send samples to a laboratory. Test results are directly related to calcium and magnesium concentrations, providing relevant information for adjusting or verifying water softening and conditioning systems.

Suitable for

• Household checks of mains water hardness before installing water softeners
• Routine verification of water hardness after maintenance of filtration or softening systems
• Pre-checks by technicians during installation and commissioning of water treatment equipment
• Basic water quality diagnostics for domestic appliances sensitive to scale (boilers, kettles, washing machines)

Key specifications

• Measurement target: water hardness related to calcium and magnesium
• Form factor: portable test kit with reagents and manual testing tools
• Intended use: on-site, rapid visual determination of hardness level
• Application environment: household and light professional/installation use

How to use

Collect a sample of tap water in a clean container according to the kit instructions. Add the specified amount of reagent to the sample and mix as described in the supplied procedure. Observe the colour change or measurement indicator to determine the hardness level, comparing the result to the kit’s reference chart. Perform tests on fresh samples and follow the kit’s safety and storage guidance for reagents. Dispose of used reagents and containers in accordance with local regulations.

Usage recommendations

For reliable results, test water at room temperature and avoid contaminating samples. Use the kit before any adjustment or commissioning of softening equipment and repeat measurements after changes to system settings or maintenance. Store reagents in a cool, dry place and follow expiry and handling instructions provided with the kit.
