HANNA Ultra Low Range Phosphate Colorimeter - Checker® HC
  • The HI774 Checker® HC Mini Photometer offers a simple, accurate, and economical way to measure phosphates in marine systems, including coral reef aquariums. Phosphates are an important parameter to measure in aquaculture and aquaria; levels that are too high can lead to algal blooms and dissolved oxygen depletion which in turn smothers aquatic life.
