pH of ocean surface water is normally 7.5.to 8.5 pH. Over the years however, acidification tendency is to decrease 0.1 to 0.2 pH units/century. Acidification is a consequence of carbon dioxide (CO?) absorbtion in seawaters and oceans. Carbon dioxide reacts with seawater to produce carbonic acid (H?CO?).
pH modifications affect marine life growth, reproduction, and communication. Hydrogen ions have a tendency to bond with carbonate to form bicarbonate. The greater attraction to carbonate over calcium can adversely affect skeleton building and can limit coral growth.
The HI780 Checker HC is a simple, accurate, and cost effective way to measure pH in seawater. Designed as a more accurate alternative to chemical test kits, this handheld colorimeter provides quick, accurate pH testing results.
- Ideal for aquariums and marine biology
- Easier to use and more accurate than chemical test kits
