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.

Absolutely. We use this as a backup to our GHL KH Director and they're both within .2 of each other. Nice to have a backup.

REVIEW
Used all different test kits and Hanna is the best. Simple and easy to use. I really like that instead of having to buy an entirely new kit, that just the reagents are available for restocking.

REVIEW
I've been using the Hanna Alkalinity Checker for the past year and I'm running low on reagent so of course it was time to restock. The checker itself is pricey, but the reagent itself is affordable so it's great in the long run.
