Description
To evaluate alkalinity, use the HI755 Checker®HC (Handheld Colorimeter), which is easy to use, precise, and reasonably priced. Alkalinity is essential in marine environments because it offers the carbonate ion needed for coral reefs to regenerate their calcium carbonate skeletons as well as a pH buffer against significant acidity fluctuations.
The HI755 was created as a more precise substitute for chemical test kits and offers quick, precise alkalinity results in four simple steps:
Features
- Easier to use and more accurate than chemical test kits
- Dedicated to a single parameter
- Small size, big convenience
