774 Checker
The HI774 Ultra Low Range Phosphate Checker HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure phosphate in marine systems including reef tanks.

Designed as a more accurate alternative to chemical test kits, the HI774 provides quick, accurate results in a few easy steps.
