The HI772-26 are the replacement reagents Marine Alkalinity (dKH) Checker® HC - HI772. These high-quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.

Details:

The HI772-26 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Marine Alkalinity Checker® HC. These reagents follow the Colorimetric Method in which the reaction causes a distinctive range of colors from yellow to green to blue to develop. By simply adding the solution of HI772-26 to the sample, the reaction will take place and the Marine Alkalinity Checkers will determine the concentration from the color that is produced. The results will be displayed in dKH for the HI772 Checker . These reagents are designed to be used with samples that have an expected range of 0.0 to 20.0 dKH.

Hello, Here you go. Per Hanna " Hi there, We updated the reagent product code used for the HI772 dKH Alkalinity Checker. The new code is: HI772-26 Marine Alkalinity Checker‚® HC Reagents for HI772 (25 Tests) hannainst.com/marine-alkalinity-checkerr-hc-reagents-25-tests.html This have been updated from the HI755-26. The chemical used is still the same we just created a new code to match our reagent categorization system. The HI755-26 Alkalinity reagent for the ppm Marine Checker is still an active code and the reagents can be used interchangeably. Thank you for testing with Hanna Instruments!" Have a wonderful day.
