Hanna HI720-11 Calcium Hardness Checker HC

Hanna HI720-11 Calcium Hardness Checker HC Calibration Standards

The Hanna HI720-11 is a high-quality calibration check set designed to verify the accuracy of the HI720 Calcium Hardness Checker HC. This set includes two sealed cuvettes—one with 0.00 ppm calcium hardness (as CaCO₃) and one tinted to simulate a known standard concentration (typically 2.00 ± 0.20 ppm CaCO₃ @ 25°C*).

Manufactured in a temperature-controlled environment using reagent-grade chemicals, this calibration set ensures traceability, reliability, and long-term performance. It is ideal for routine quality assurance in both lab and field environments.

Features

• Dual-Point Calibration: Includes both 0 ppm and a known-value standard to confirm accurate readings across the Checker’s range.

• Certified Traceability: Supplied with a Certificate of Analysis that includes reference values, lot number, and expiration date.

• Ready-to-Use: No preparation required—just insert the sealed cuvettes directly into the HI720 Checker® HC.

• Stable & Reproducible: Sealed under controlled conditions using reagent-grade materials to ensure consistent calibration performance.

• Essential for Quality Control: Ideal for maintaining compliance and confidence in water testing workflows.
