Hanna HI709 Manganese High Range Checker

Hanna HI709 Manganese High Range Checker

The Hanna HI709 Manganese High Range Checker is a compact, digital colorimeter designed to provide quick, accurate, and affordable measurement of manganese in water samples. Whether used in water treatment facilities, environmental monitoring, or industrial applications, the HI709 bridges the gap between basic chemical test kits and advanced laboratory instrumentation.

Using an adaptation of the Periodate method from the 18th edition of Standard Methods for the Examination of Water and Wastewater, the device produces a pink color in the presence of manganese, which is then digitally quantified using an LED light source at 525 nm and a silicon photocell detector. With its palm-sized design and straightforward operation, the HI709 delivers lab-quality results in just minutes.

Features

• High Range Manganese Detection (0.0 to 20.0 ppm)
  Perfect for monitoring manganese in applications where higher concentrations are expected or allowed.

• Reliable and Accurate Readings
  Accuracy of ±0.2 ppm ±5% of reading with 0.01 ppm resolution provides confidence in each result.

• EPA-Based Analytical Method
  Utilizes the Periodate method, ensuring consistency with standardized testing protocols.

• Compact and Portable
  Weighing just 64 g and fitting comfortably in the palm, it’s ideal for fieldwork and on-site testing.

• Simple One-Button Operation
  Minimal training required—easy to operate with intuitive steps and clear digital output.

• Auto-Off Function
  Powers down automatically after 10 minutes of inactivity to preserve battery life.

• Battery Included
  Powered by a single 1.5V AAA battery, ensuring long-lasting usability and immediate operation out of the box.

Applications

• Drinking Water Monitoring
  Ensures manganese levels comply with health and safety regulations.

• Wastewater and Effluent Testing
  Detects high manganese concentrations in industrial discharge and treatment facilities.

• Environmental Monitoring
  Tracks manganese in rivers, lakes, and groundwater as part of pollution control or remediation projects.

• Industrial Process Water
  Verifies manganese content in water used for manufacturing, boiler systems, and cooling towers.

• Mining and Metallurgical Applications
  Monitors manganese concentrations in ore processing and wastewater streams.
