Hardness Test Strips, Hach
Product Code: 27452
These are typically ordered from Hach as required to allow for fresh dating. Please allow an extra 10 days for delivery.
The Hach 27452 Total Hardness Test Strips provide a quick and convenient method for measuring total water hardness without requiring a titration kit or laboratory instrumentation. The strips measure hardness from 0 to 425 mg/L (ppm) as CaCO₃, making them useful for rapid screening of freshwater sources, aquaculture systems, laboratories and environmental field samples. Hach identifies the product as its total hardness test strip, catalogue 27452-50.
The colour-change test provides readings at 0, 25, 50, 120, 250 and 425 mg/L as CaCO₃. The strips are particularly useful when a fast indication of water hardness is needed in the field, without the additional glassware, reagents and endpoint determination associated with titration methods.
