The Hanna Phosphate Ultra Low Range (0.00 to 0.90 ppm) 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 Phosphate 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
- Built-in Timer
- One-Button Operation
The HI774 Checker® HC (Handheld Colorimeter) 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 that would like measure phosphate as phosphorous we off the HI736 Phosphorous Checker® HC. Alternatively, to determine the fraction of phosphorous (PO4-P) there is 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 phosphorous.
