Turbidity Standards

April 3, 2018
U.S. EPA approval was recently awarded for the new line of primary turbidity standards manufactured by HF scientific. The stable and easy-to-use ProCal standards will replace the Primetime standards currently used in the company’s products. The standards are being certified for use in other manufacturers’ instrumentation. Soon almost any turbidity instrument will be able to be calibrated using the pre-diluted, factory-certified turbidity standards.
