Hach® LZY837 Stablcal Calibration Vial 20 NTU, For use with TU5200, TU5300sc, and TU5400sc Laser Turbidimeters

Item Features

• 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.
