Phosphorus Handheld Colorimeters
- Easier to use and more accurate than chemical test kits
- Dedicated to a single parameter
- Small size, big convenience
- Ideal for aquaculture
Plants, algae and phytoplankton require phosphorus for nourishment and utilise phosphorous as a component of cell tissue. When organic matter such as plant tissue, dead fish, algae, or uneaten food breaks down aerobically (with oxygen), phosphate is produced, This results in rapid oxygen depletion of aquarium water, which in turn suffocates aquatic life and compounds the problem.
Phosphorus concentration in water is monitored because it causes corrosion when present in levels too high.
Both the Hanna HI736 and HI706 Checker®HC’s bridge the gap between simple chemical test kits and professional instrumentation. The Hanna HI736 (for marine applications) and HI706 (for fresh water applications) are both accurate and affordable.
The HI736 Checker®HC portable handheld colorimeter features a resolution of 1 ppb and ±5 ppb ±5% of reading accuracy and uses an adaptation of the Ascorbic Acid.
