Stablcal® Stabilized Formazin Turbidity Standards-HACH 2788453

USEPA accepted for calibration purposes. Stablcal® Stabilized Formazin Turbidity Standards are true Formazin dilutions developed for use in any turbidimeter. • Precise, Pre-mixed Formazin Solutions - With proprietary manufacturing technology, Hach prepares Stablcal Standards in precise concentrations at a wide variety of concentrations - providing accurate turbidimeter calibrations. • Based on Formazin Primary Standards - Stablcal Stabilized Formazin Standards contain the same light scattering polymer as traditional Formazin primary turbidity standards - and perform equivalently. • Enhanced Stability Saves Time and Labor - While Formazin primary standards can be prepared directly in the lab, the process is labor intensive and time consuming - and the diluted standards are not stable. Stablcal is a stabilized version of Formazin - providing repeatable results, without the time and effort required for lab-prepared standards. • Confidence in results - Hach was the first to apply Formazin as a turbidity standard in the drinking water industry, more than 40 years ago. Stablcal standards are based on decades of experience in turbidity measurement.
