The Hanna Phosphorus Colorimeter Checker (ULR) HI736 (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure phosphorus in marine systems including reef tanks.
Phosphorus 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.
Phosphorus concentration in water is monitored because it causes corrosion when present in levels too high.
The HI 736 Checker HC portable handheld colorimeter features a resolution of 1 ppb and ±5 ppb ±5% of reading accuracy and uses an adaptation of Standard Method Ascorbic Acid.
The HI 736 Checker HC is extremely simple to use. First, zero the instrument with your water sample. Next, add the reagents. Last, place the vial into the Checker®HC, press the button and read the results. It’s that easy.
