Hanna HI719-11 Magnesium Hardness Checker

Hanna HI719-11 Magnesium Hardness Checker HC Calibration Standards

The Hanna HI719-11 is a precision calibration check set designed to validate the accuracy of the HI719 Magnesium Hardness Checker HC. This set includes two sealed cuvettes: one with 0 ppm CaCO₃ and one tinted to simulate a 1.00 ± 0.20 ppm CaCO₃ magnesium hardness standard at 25°C.

Manufactured using reagent-grade chemicals in a temperature-controlled environment, this calibration set offers a reliable method to ensure the performance of your magnesium hardness Checker is consistently accurate. It is ideal for use in quality control, field validation, and laboratory environments.
