Hanna HI723 Chromium VI High Range Checker HC

Hanna HI723 Chromium VI High Range Checker HC – Handheld Colorimeter for Hexavalent Chromium

The Hanna HI723 Chromium VI High is a portable digital colorimeter specifically engineered for accurate measurement of hexavalent chromium (Cr⁶⁺) in water samples. Known for its toxicity and environmental impact, Chromium VI must be precisely monitored in industrial discharge, environmental samples, and drinking water to comply with regulatory limits and ensure safety.

Using the well-established diphenylcarbohydrazide colorimetric method, this handheld colorimeter delivers quick, reliable, and laboratory-grade results in just a few steps. It is a preferred alternative to conventional chemical test kits, offering enhanced accuracy and ease of use for professionals and field technicians alike.

Key Features

• Accurate and Reliable
  Measures Chromium VI levels with ±5% of reading ±4 ppb accuracy, offering confidence in every result.

• High Sensitivity
  Delivers a 1 ppb (µg/L) resolution, ideal for detecting trace levels of Chromium VI in sensitive applications.

• Diphenylcarbohydrazide Method
  Employs a trusted EPA-adapted method, in which a reaction with the reagent forms a violet-colored complex measured photometrically.

• User-Friendly Interface
  Large, clear digital display and one-button operation simplify the testing process—even for non-technical users.

• Portable and Lightweight
  Compact design fits in your hand or tool kit, enabling easy field deployment and on-site analysis.

• Auto Shut-Off
  Conserves battery life with a built-in power-down feature after 10 minutes of inactivity.

Applications

• Drinking Water Testing
  Ensures compliance with national and international safety standards for potable water.

• Industrial Effluent Monitoring
  Tracks chromium discharge in industries such as electroplating, textile dyeing, and metal finishing.

• Environmental Field Testing
  Used in rivers, lakes, and groundwater testing for contamination assessment and ecological protection.

• Academic and Research Labs
  Supports accurate and repeatable analysis in water quality and environmental science studies.
