Hanna Instruments Saltwater Aquarium Ultra Low Range Phosphorus Colorimeter (HI736)

The Hanna Instruments HI736 is a handheld colorimeter designed to accurately measure ultra-low phosphorus levels in saltwater aquariums. It uses digital colorimetry technology to provide more precise and reliable readings than traditional test kits, eliminating visual subjectivity.

What is it used for?

Phosphorus in saltwater aquariums is a critical factor affecting water quality and overall ecosystem health. This colorimeter is ideal for:

• Monitoring and controlling phosphorus buildup that can lead to unwanted algae growth.
• Preventing water quality issues in reef aquariums and saltwater systems.
• Optimizing the use of filtration media to reduce excess nutrients.

High phosphorus levels can cause algae blooms and negatively impact corals and fish. Regular monitoring allows for corrective actions before levels become problematic.

How to use it?

1. Prepare the sample – Collect an aquarium water sample in the provided cuvette.
2. Add the reagents – Mix the reagent powder with the sample as instructed.
3. Measure the sample – Place the cuvette into the Checker and press the button for analysis.
4. Read the results – Within seconds, the display shows the exact phosphorus concentration in ppb (parts per billion).
