The Hanna Phosphorus Ultra Low-Range (0 to 200 ppb) Checker® bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in color. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light sensing detector to precisely determine ion concentration. Professional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Hanna Phosphorus Ultra Low-Range Checker® uses a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.
Compact, Portable Design
The HI736 Checker® HC (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. Designed as a more accurate alternative to chemical test kits, the HI736 provides quick, accurate results in four easy steps:
Easier to use and more accurate than chemical test kits
Dedicated to a single parameter
Small size, big convenience
Ideal for: Aquariums, Environmental, Aquaculture, Water Quality
