Water Hardness DUO Titration Kit – Flexible Hardness Analysis For precise measurement of water hardness The Water Hardness DUO Titration Kit is designed to measure water hardness in raw water (30–80 °dH) and treated water (0–2 °dH). With the DUO kit, you can reliably determine the hardness of both raw and treated water. The set includes all necessary reagents and accessories for immediate use. Precise Determination of Water Hardness in Raw and Treated Water The Water Hardness DUO Titration Kit provides a flexible and reliable analysis of water hardness for both raw and treated water. It covers a wide measurement range from 30–80 °dH in raw water and 0–2 °dH in treated water, making it ideal for various applications in water treatment. The kit is designed for users who require fast and accurate hardness measurements, whether for untreated raw water or softened water. Advantages of the Water Hardness DUO Titration Kit With the DUO titration kit, two measurement ranges can be covered with a single set. This reduces the need for separate measurement systems and allows efficient monitoring of water hardness before and after treatment. The set includes all necessary reagents and accessories for immediate use. The manual titration method delivers precise and reproducible results and is particularly suitable for control measurements, commissioning, or mobile applications in water analysis.
