The CCOH Polyamine Test Kit is used to determine the polyamine concentration in circulating water. This polyamine test kit is a titration set. The CCOH Polyamine Test Kit is a set for determining polyamines in water. The test kit for polyamine determination works according to the principle of titration. All polyamine test kits use a pipette calibrated in the range of 0 to 60 mg/l (resolution: 1 mg/l). If needed, a second pipette filling can be added, extending the measurement range up to 120 mg/l (K26). Visible measurement of polyamines in water A water sample is taken with the test kit, the appropriate reagents are added, and the color change is observed. Approximately 100 analyses can be performed at an average concentration of 30 mg/l, with a measurement time of about 3 minutes. Please read the enclosed instructions carefully. Features at a glance Manual determination of polyamine content without electronic devices Color change for simple and direct reading Fast results within a short time Compact all-in-one solution with reagents Analyses: approx. 100 (at an average content of 30 mg/l) Measurement time: approx. 3 minutes Resolution: 1 mg/l

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. Frequently asked questions How long do Heyl chemicals last? The shelf life is printed on the label of each product. Upon delivery, the guaranteed shelf life is at least 7 months.
