LF Kit for Total Hardness Analysis in Water

A total hardness analysis kit measures the concentration of dissolved minerals, primarily calcium and magnesium, in water. These minerals enter the supply through natural geological layers, and their levels affect everything from the taste of beverages to the lifespan of equipment. The kit uses a chemical reaction that changes colour in proportion to the mineral content, allowing the operator to compare the sample against a calibrated scale. This method is simple, visual and does not require electricity or laboratory conditions, making it practical for daily use in a busy kitchen or bar.

To use the kit, the operator fills a clean test tube with a measured volume of water from the tap, boiler or filtration system. A reagent is added drop by drop, swirling the tube after each drop until the colour shifts from one hue to another. The number of drops needed to reach the endpoint indicates the hardness level. The result is read directly from the supplied chart, which translates the colour into parts per million or degrees of hardness. No calculations are required, and the entire sequence takes less than a minute.

The kit is supplied complete with reagents, test tubes, a colour comparison chart and instructions. It is designed for repeated use, with reagents that can be replenished separately. Regular testing helps maintain consistent water quality, which in turn protects appliances such as combi ovens, steamers and coffee machines from scale build-up and ensures beverages taste as intended.

This particular kit is referenced by BRITA for compatibility with their professional water filtration systems, allowing operators to verify the performance of filters and decide when replacement cartridges are needed. It is a standard tool in catering environments where water quality directly affects both product and equipment.
