Hanna HI97734-11 Free and Total Chlorine High Range CAL Check™ Standards are precision calibration and validation solutions designed specifically for use with the HI97734 portable photometer. These standards ensure accurate and reliable measurement of free and total chlorine across the high range of 0.00 to 10.00 mg/L, making them essential for maintaining instrument performance in laboratory, industrial, and field applications.

The set includes two sealed calibration standards with values of 0.00 mg/L and 4.00 ±0.20 mg/L chlorine, enabling users to verify photometer accuracy and validate measurement consistency. Manufactured in a controlled environment using high-quality materials, these standards provide stable and reproducible reference points for calibration procedures.

Each kit is supplied with a Certificate of Analysis, detailing the lot number, certified reference values, and expiration date. This ensures full traceability and supports compliance with Good Laboratory Practice (GLP) and regulatory quality systems. The sealed design prevents contamination and extends shelf life, while allowing the standards to be reused for multiple verification cycles.

Designed for ease of use, the HI97734-11 standards allow quick and reliable calibration checks without complex preparation steps, helping reduce downtime and improve workflow efficiency. They are widely used in water treatment plants, environmental laboratories, industrial quality control, and municipal water testing facilities where accurate chlorine monitoring is critical.
