Hanna HI721-11 Iron Checker HC

Hanna HI721-11 Iron Checker HC Calibration Standards

The Hanna HI721-11 is a certified calibration check set designed to validate the performance of the HI721 Iron Checker HC. This set includes two sealed cuvettes—one with 0.00 ppm iron and the other with a standard solution tinted to simulate 1.00 ± 0.05 ppm iron at 25°C. As a result, users can quickly verify the accuracy and reliability of their instrument in both laboratory and field settings.

Because accuracy is critical in water testing applications, this calibration set is manufactured using reagent-grade chemicals in a temperature-controlled environment. In addition, every set includes a Certificate of Analysis, providing full traceability through lot numbers, reference values, and expiration dates.

Features

• Dual-Point Calibration: Includes 0.00 ppm and 1.00 ± 0.05 ppm iron standards to ensure your Checker® HC is functioning correctly across its range.

• Certified Traceability: Supplied with a Certificate of Analysis to support QA/QC programs and compliance reporting.

• Ready to Use: The sealed cuvettes require no mixing or preparation—simply insert into the checker and verify performance.

• Stable & Reproducible: Reagent-grade standards ensure consistent results across repeated checks.

• Ideal for Routine Validation: Particularly useful for labs, technicians, and field testers who require high-confidence measurements.
