Hanna Freshwater Alkalinity Checker HC® Calibration Check Set - HI775-11

HI775-11 Freshwater Alkalinity Checker HC Calibration Check Set is a high-quality validation kit designed to ensure the accuracy of freshwater alkalinity measurements using Checker HC series photometers. The calibration set includes one sealed cuvette for zero ppm CaCO₃ and one for 100±10 ppm CaCO₃, both manufactured for traceable laboratory use and supplied with a Certificate of Analysis.

Each kit allows users to routinely verify instrument calibration and maintain rigorous quality standards in laboratory, water testing, environmental research, and industrial process monitoring. The standard value of 100 ±10 ppm CaCO₃ at 25℃ closely matches typical freshwater alkalinity testing ranges.
