Description

ProCal Primary Turbidity Standards are pre-diluted, factory certified, and ready for use with not only the HF scientific turbidimeter product line but with other manufacturer's instrumentation. The ProCal no formazin formulation utilizes a preservative that enhances stability, yet is safe and biodegrades rapidly in aquatic environments.
