Ultra-Low Range Total Hardness Testing for High-Purity Water
The Hardness (ULR) Reagent Set, Solution Pillows (2603100) is designed for ultra-low range measurement of calcium and magnesium hardness in high-purity water applications using the Chlorophosphonazo colorimetric method (Hach Method 8374, DOC316.53.01044).
This reagent set enables accurate determination of total hardness as CaCO₃ at concentrations far below traditional titration. Hardness (ULR) Reagent Set, Solution Pillows (2603100) are designed for ultra-low range measurement of calcium and magnesium hardness in high-purity water applications
Key Features & Benefits Ultra-Low Range Hardness Detection Measures total hardness over the range of: 8 - 1000 µg/L Total hardness as CaCO₃ using a standard plastic cell (PN 2410222)
Ideal for High-Purity Water Applications Designed for monitoring trace hardness in: • Municipal pretreatment • Membrane protection • Groundwater and source water monitoring • Reverse osmosis (RO) systems • Demineralizer trains • High-pressure boiler systems • Semiconductor and ultrapure water processes • Zeolite water softening system • Pharmaceutical (makeup water)
