Hach Stablcal Turbidity Standards allow you to stay compliant with your turbidity readings. Hach offers a wide range of turbidity standards designed for use in any turbidity meter. All Stablcal standards are USEPA accepted for calibration purposes and provide you with highly accurate results ensuring the high purity. Ready-to-use Standard Solutions have the concentration in the range from < 0.1 NTU to 10000 NTU. Most solutions are available in 500 ml or 1 liter bottles or in easy-to-use sealed vials. The vials have a long shelf life and can be used for an unlimited number of calibrations and verifications within their expiration date. Hach Stablcal Turbidity Standards contain the identical light scattering polymer as conventional Formazin Primary Turbidity Standards featuring equivalent efficiency. Stablcal Stabilized Formazine Turbidity Standards provide increased stability saving time and labor required for preparation of such standards in the laboratory.
