Hanna Checker HI780 photometer for pH in seawater

Hanna Checker HI780 for pH in seawater

pH fluctuations affect the growth, reproduction and communication of marine life. Hydrogen ions tend to bind to carbonate to form bicarbonate. The greater attraction for carbonate over calcium can adversely affect skeletal structure and limit coral growth. The HI780 Checker is a simple, accurate and cost effective way to determine the pH of seawater. Developed as the accurate alternative to chemical test kits, the Hanna Instruments Checker provides fast, reliable measurement results in four easy steps. The checkers are designed in such a way that they are comfortable to hold, easy to carry and easy to read due to the large display.

• Easier and more accurate than chemical test kits
• Practical pocket size
• Clearly readable display
• Simple one-button operation
• Auto power off
• Operates on a single AAA battery
• Best to measure the pH just before the lighting comes on, then the pH is at its lowest level
