Viscosity Standards

Viscosity Standards are certified reference materials used for the precise calibration and verification of viscometers, rheometers, and other viscosity measurement instruments. Manufactured to ISO 17025 and ISO 17034 requirements and traceable to NIST standards, they ensure accurate, reproducible results in quality control, research, and industrial applications. Available in a wide range of kinematic viscosities and temperature ranges, these calibration fluids meet ASTM D445, DIN 51562, and other international methods, making them essential for petrochemical testing, pharmaceutical formulation, food and beverage quality control, paint and coating analysis, and lubricant evaluation.
