Turbidity Standards

Turbidity Standards are certified reference solutions used for the accurate calibration and verification of turbidity meters and nephelometers in compliance with ISO 7027 and US EPA 180.1 methods. These stable, ready-to-use standards ensure precise measurement of turbidity in Nephelometric Turbidity Units (NTU), enabling reliable monitoring of water clarity and particle content. From water treatment plants and environmental monitoring laboratories to food and beverage quality control and pharmaceutical manufacturing, turbidity standards guarantee consistent, traceable results that meet regulatory requirements. Often used alongside rapid water analysis tools such as HydroSense systems, they provide a dependable benchmark for field and laboratory testing. Available in a range of NTU values, they offer long-term stability and reproducibility, helping maintain instrument accuracy, process control, and product quality.
