Hanna Checker HI780 for pH in seawater

Understanding pH fluctuations is crucial as they can significantly influence the growth, reproduction, and communication of marine life. When hydrogen ions bind to carbonate, they form bicarbonate, which can lead to a greater attraction for carbonate over calcium. This situation may negatively impact skeletal structure and hinder coral growth.

The HI780 Checker offers a straightforward, accurate, and cost-effective solution for measuring the pH of seawater. Designed as a reliable alternative to traditional chemical test kits, the Hanna Instruments Checker delivers quick and dependable measurement results in just four easy steps. Its comfortable design makes it easy to hold and carry, and the large display ensures that readings are easy to read.
