Hanna Anionic Surfactant CAL Check™ Standards - HI97769-11

Hanna Instruments HI97769-11 Anionic Surfactant CAL Check Standards are specialized calibration and validation vials designed for use with the HI97769 portable photometer. This set includes sealed standards for 0.00 mg/L and 1.00 mg/L SDBS (sodium dodecylbenzenesulfonate), enabling accurate and dependable photometric measurement of anionic surfactants in water samples. These calibration standards are compatible with photometers operating within a 0.00 to 3.50 mg/L (ppm) range as SDBS.

Each standard is produced under controlled conditions to ensure consistency and is supplied with a certificate of analysis detailing the lot number, reference values, and expiration date, supporting full traceability and compliance during calibration and certification processes.

The set contains two reusable sealed vials for calibration verification at 0.00 mg/L and 1.00 mg/L SDBS at 25℃. It ensures precise and consistent calibration when measuring anionic surfactants through photometry, making it suitable for laboratory and environmental field applications. It enables fast and accurate validation for HI97769 photometers used in compliance testing, water monitoring, and analytical laboratories.

With a long shelf life and reusable design, these standards help reduce operational costs while maintaining reliable performance. The included certificate of analysis supports detailed traceability for quality audits and calibration documentation. These standards are suitable for water laboratories, industrial analysis, compliance environments, and service providers.

These calibration standards support consistent and reproducible results for regulatory compliance and quality assurance. Explore laboratory calibration solutions and Cal Check Standards for precise and reliable measurement support.
