Hanna Ammonia Medium Range CAL Check™ Standards - HI97715-11

Hanna HI97715-11 Ammonia Medium Range CAL Check™ Standards are precision calibration solutions designed for accurate validation and calibration of HI97715 ammonia photometers. Engineered to ensure reliable instrument performance, these standards support consistent and accurate ammonia measurement in laboratory, industrial, and environmental applications.

This set includes two sealed cuvettes: one zero standard (0.0 mg/L) for instrument baseline adjustment and one calibration standard at 6.0 ±0.050 mg/L ammonia (as NH₃-N) at 25°C. These certified values enable users to perform accurate calibration and verification procedures, ensuring dependable photometric results.

Each set is supplied with a Certificate of Analysis, providing complete traceability with detailed information such as lot number, certified reference values, and expiration date. This makes the standards suitable for regulated environments where documentation and quality assurance are critical.

Designed for convenience and efficiency, the sealed cuvettes prevent contamination and maintain solution integrity over time. The reusable design with excellent long-term stability makes this set a cost-effective solution for routine calibration and validation tasks.

These CAL Check™ Standards are widely used in water treatment plants, environmental monitoring programs, research laboratories, and industrial quality control processes where accurate ammonia measurement is essential. They help maintain instrument accuracy, reduce measurement errors, and support compliance with analytical standards.

Ensure consistent and reliable photometer performance with Hanna’s certified calibration standards, developed for precision, stability, and traceability in professional applications photometer calibration standards.
