Hanna Phosphate Ultra Low Range Checker HC – HI774

Marine Phosphate Ultra Low Range Checker HC – HI774 Test-kit

The HI774 Checker® HC (Handheld Colourimeter) provides a simple, accurate and cost-effective way to measure phosphate in marine systems, including coral reef tanks. Phosphate is an important parameter to measure in aquaculture and aquariums; levels that are too high can lead to extensive algae growth, depleted dissolved oxygen levels, and ultimately can be fatal to many types of fish and aquatic life. Designed as a more accurate alternative to chemical test kits, the HI774 provides quick, accurate results. For those who would like to measure phosphate as phosphorus, we offer the HI736 Phosphorus Checker® HC. Alternatively, to determine the fraction of phosphorus (PO4-P) in phosphate (PO43-), the phosphate reading is multiplied by 0.3261. A 0.50 ppm phosphate reading is equal to 0.163 ppm or 163 ppb phosphorus. 

• More accurate than chemical test kits.
• No errors with a digital readout.
• Ideal for aquariums and marine biology applications.

Very low levels of nitrate are critical for many saltwater reef aquariums
