Hanna HI706 Phosphorous HR Checker HC

Hanna HI706 Phosphorous HR Checker HC

The Hanna HI706 Phosphorous HR Checker HC is a compact, digital colorimeter developed for accurate and affordable phosphorus testing in freshwater environments. Designed to fill the gap between basic chemical test kits and advanced laboratory instruments, the HI706 delivers reliable high-range phosphorus measurements in just a few simple steps. Its lightweight, palm-sized design makes it the perfect tool for on-site or laboratory use in aquaculture, water quality control, and environmental monitoring.

This checker uses an adaptation of the Heteropolymolybdenum Blue method from the 18th edition of Standard Methods for the Examination of Water and Wastewater. In this method, phosphorus reacts with the reagent to produce a blue tint, which is then measured by the instrument’s LED light source and silicon photocell to determine the phosphorus concentration accurately.

Features

• High Range Measurement (0.00 to 15.0 ppm)
  Specifically engineered for high-level phosphorus detection in freshwater systems.

• Accurate and Reliable Readings
  Offers an accuracy of ±0.3 ppm ±5% of reading and a resolution of 0.1 ppm, making it a reliable alternative to visual testing.

• Compact and Lightweight Design
  Fits comfortably in your hand or pocket—ideal for both lab technicians and field professionals.

• One-Button Operation
  Extremely simple to use; no prior technical expertise required to obtain reliable results.

• Digital LCD Display
  Eliminates subjectivity by presenting clear numerical values instead of color comparisons.

• Auto Power-Off Feature
  Shuts off automatically after 10 minutes of inactivity to extend battery life.

• Starter Kit Included
  Supplied with reagents for 20 tests, 2 sample cuvettes with caps, AAA battery, and user instructions.

Applications

The HI706 Phosphorus Checker is a valuable tool for professionals and enthusiasts in various freshwater monitoring applications:

• Freshwater Aquaculture and Aquariums
  Ensures safe phosphorus levels to support aquatic health and minimize algae growth.

• Environmental Water Testing
  Monitors nutrient loading and phosphorus pollution in lakes, rivers, and streams.

• Educational and Research Laboratories
  Provides a reliable and portable solution for student labs or field research activities.

• Agricultural Runoff Monitoring
  Detects phosphorus in runoff that can contribute to eutrophication in nearby water bodies.
