Hanna Anionic Surfactant CAL Check™ Standards - HI97769-11

HI97769-11 Anionic Surfactant CAL Check Standards are specialized calibration and validation vials designed for use with the HI97769 portable photometer. This set contains sealed standards for 0.00 mg/L and 1.00 mg/L SDBS (sodium dodecylbenzenesulfonate), facilitating accurate and reliable photometric measurements of anionic surfactants in water samples. The calibration standards are compatible with photometers utilizing a 0.00 to 3.50 mg/L (ppm) range as SDBS.

Each standard is manufactured in a state-of-the-art facility for reproducibility and comes supplied with a certificate of analysis indicating the lot number, reference values, and expiration date, supporting full traceability and regulatory compliance during certification and calibration.

• Set contains two reusable sealed vials for calibration verification: 0.00 mg/L and 1.00 mg/L SDBS at 25℃.
• Ensures consistent and precise calibration when measuring anionic surfactants by photometry, ideal for laboratory and environmental field applications.
• Enables fast and accurate validation routines for HI97769 photometers in compliance testing, water monitoring, and analytical laboratories.
• Long shelf-life and reusable design lower total laboratory operating costs while maintaining trusted performance.
• Certificate of analysis provides detailed traceability for quality audits and calibration documentation.

Appropriate for water laboratories, industrial analysis, compliance environments, and photometer manufacturers or service providers. Explore more Laboratory Calibration Standards and precision photometric accessories on EnvMart.
