Stablcal standards are based on decades of experience in turbidity measurement. With proprietary manufacturing technology, Hach prepares Stablcal Standards in precise concentrations at a wide variety of concentrations - providing accurate turbidimeter calibrations.

This pre-packaged and ready to use Stablcal Formazine Reference Suspension with a volume of 100 mL and a concentration of 3 NTUs is certified and stable for 2 years.

The Barnant 246142 formazin standard solution has a 4000 NTU turbidity and is used for calibration of turbidimeters.

Thermo Scientific™ Remel Colorimeter Standard Kit contains latex equivalence turbidity standards for use with Vitek colorimeter.

Thermo Scientific™ Remel McFarland Equivalence Turbidity Standard is packaged in plastic case with a visual comparison card.

Simple, display-prompted push-button calibration

Use turbidity standards for precise measurements with nephelometeric instruments. Non Ratio Turbidity Standards, Reagecon™ are composed of suspended polymer microspheres to eliminate the problems with Formazin standards. They are NIST traceable, US EPA approved and certified accurate to ±1%.

For use with TB300-IR Lab Turbidimeter.
