Product Description
Our HI774 Ultra Low Range Phosphate Checker will be essentially the same specifications as the HI736 Ultra Low Range Phosphorus Checker however it will not require a conversion but read directly in parts per million phosphates compared to parts per billion phosphorus.
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. 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 in a few easy steps.
