What is Hanna Phosphorus Pocket Checker?

The Hanna Phosphorus Pocket Checker is ideal for salt water aquariums and coral reef tanks. Specially designed for salt water, the HI-736 Phosphorus Checker will measure vital phosphorus levels - even at exceptionally low range. The checker is supplied with reagents for 6 tests.

Specially designed for salt water, the Phosphorus Checker will measure vital phosphorus levels - even at exceptionally low range. Phosphorus (as phosphate) is introduced through feed, decaying plant and animal waste and even tap water. However phosphate is a driving factor in excess algae growth and without adequate checks, the phosphate can quickly become so abundant that it turns into a real nuisance.

For healthy aquatic life it is important to keep levels as close to zero as possible. The Hanna Checker now makes it possible for salt water fish enthusiasts to maintain ultra low levels at genuinely affordable prices.

Key Features:

  • Range from 0 to 200 ppb
  • Testing is quick and easy
  • High precision results - more accurate than chemical test kits
  • Auto shut-off feature means the Checker cannot be left on by mistake
  • Fully portable, fitting easily into both palm and pocket

What are Phosphorus Reagents?

Also available to purchase are the replacement reagents for this device that come available as a pack of 25. Hanna Replacement Reagents are high-quality reagents for Hanna chemical test kits and Hanna instruments, which are designed to identify different chemicals within your aquarium or pond. These high-quality reagents are pre-measured, allowing users to achieve fast and accurate measurements with each of their pocket checkers. These reagents follow the DPD Method in which the reaction between the element and reagent causes a tint in the sample. By simply adding the packet of reagent to the sample, the reaction will take place and you can determine the concentration from the colour that is produced. The results will be displayed on the pocket checker LCD screen.
