ProCal Turbidity Standards for HF Scientific Meters
   
ProCal primary turbidity standards are pre-diluted, factory certified and ready-to-use.

The ProCal standard formulation utilizes a preservative that enhances stability but is safe and biodegrades rapidly in water.

Standards are available for Hach and HF Scientific instruments.
