Hanna HI717 Phosphate HR Checker HC

Hanna HI717 Phosphate HR Checker HC

The Hanna HI717 Phosphate HR Checker HC is a compact, digital colorimeter engineered to deliver precise and reliable measurements of high phosphate concentrations in water samples. Developed as an accurate alternative to traditional chemical test kits, this handheld device combines advanced photometric technology with ease of use—ideal for both professionals and enthusiasts monitoring water quality in industrial, environmental, and aquaculture settings.

Using an adaptation of the Amino Acid method from the Standard Methods for the Examination of Water and Wastewater, the HI717 provides a clear digital reading based on the blue tint formed when phosphate reacts with the reagent. It is a valuable tool for maintaining nutrient balance and ensuring compliance with water treatment standards.

Features

• High Range Detection (0.0 to 30.0 ppm)
  Ideal for testing elevated phosphate levels commonly found in industrial discharge, wastewater, and nutrient-rich water bodies.

• Compact Handheld Design
  Pocket-sized and lightweight, perfect for fieldwork and on-site monitoring.

• Accurate and Reliable
  Delivers measurement precision of ±1.0 ppm ±5% of reading at 25°C, offering laboratory-quality results in minutes.

• Simple Operation
  Single-button interface makes the HI717 extremely user-friendly, even for those with minimal experience.

• LED Light Source and Silicon Photocell
  Ensures stable and consistent optical readings, unaffected by ambient light variations.

• Automatic Shut-Off
  Conserves battery life by powering off after two minutes of inactivity or ten seconds after displaying results.

Applications

The HI717 is suited for a wide range of applications where phosphate levels must be monitored or controlled, including:

• Aquaculture and Fish Farming
  Prevents excessive nutrient buildup and ensures aquatic life health.

• Wastewater Treatment
  Supports phosphorus removal monitoring to meet environmental discharge regulations.

• Environmental Monitoring
  Used by researchers and agencies to track eutrophication and nutrient pollution in lakes and rivers.

• Industrial and Process Water
  Ensures system efficiency and prevents scaling or biological growth.

• Educational and Laboratory Use
  Supports training and analytical testing in water chemistry programs.
