Viscosity Calibration Standards

We offer high-precision, dual-accredited viscosity standards for calibration and verification of all viscometers from glass capillary viscometers, auto viscometers, rotational viscometers, flow cups and other viscosity measuring equipment.

All viscosity standards , also called viscosity calibration standards for verification , are traceable to the primary standard of pure water, having a Kinematic Viscosity of 1.0034 mm2/s at 20 °C, as adopted by National Metrology Laboratories such as NIST and national standard bodies like ASTM, IP and ISO. All certification is carried out in accordance with ISO 17025 and ISO 17034 accreditations.

Viscosity plays a critical role in the performance of fuels, lubricants, medicines, and paints. For oils and lubricants, maintaining the correct viscosity is crucial, as degradation and fluctuations can lead to costly equipment failures and operational disruptions. Using a certified viscosity standard is essential for precise calibration and verification of viscosity measurements, ensuring the accuracy and reliability of analytical instrumentation.
