Hanna HI736-25 Phosphorus ultra low range

Hanna HI736-25 – Reagent Set for Phosphorus Ultra Low Range Checker HC (25 Tests)

The Hanna HI736-25 reagent set allows you to perform 25 ultra low range phosphorus tests using the Hanna HI736 Checker HC. These reagents are specifically formulated for high-sensitivity detection of phosphorus in water samples down to parts per billion (ppb). When paired with the HI736 device, they deliver reliable, laboratory-quality results in a compact, field-ready format.

Rather than relying on manual mixing or complex procedures, users can trust these pre-measured reagents to simplify the workflow and increase consistency.

Key Features

• Designed for Ultra Low Range Detection
  These reagents enable measurements from 0 to 200 ppb, with a resolution of 1 ppb and accuracy of ±5 ppb ±5% at 25°C—making them ideal for precision-critical applications

• Ascorbic Acid Method Compliance
  The reagents follow an adaptation of the well-established Ascorbic Acid method, where the presence of phosphorus creates a blue-colored reaction in the sample. The HI736 Checker HC then measures this color to determine phosphorus concentration.

• Simple and Safe to Use
  Each reagent is pre-measured and ready for immediate use. As a result, you can reduce chemical handling risks and eliminate the guesswork involved in manual reagent preparation.

• Reliable Results Every Time
  Because of their strict manufacturing tolerances, these reagents ensure repeatable, high-accuracy results across all 25 tests in the pack.

Specifications

• Environmental Testing
  Detect phosphorus runoff or contamination in surface water and groundwater.

• Aquaculture and Aquariums
  Keep phosphorus at safe, controlled levels to prevent algae growth and maintain optimal aquatic health.

• Laboratories and Research
  Additionally, scientists and technicians use this reagent set for water quality analysis, nutrient profiling, and ecological impact studies.

• Drinking Water Systems
  Ensure compliance with trace nutrient limits for safe potable water.
