The Cannon-Fenske Routine Viscometer is a widely used laboratory viscometer designed for the accurate measurement of viscosity in transparent liquids. Ideal for chemical, petrochemical, and research laboratories, it provides reliable and repeatable results for a wide range of viscosities.
Calibration data is provided at 40°C, 50°C, and 100°C, and each viscometer is supplied with a UKAS Certificate of Calibration (ISO 17025) to ensure traceable and certified measurements. With a nominal overall length of 250 mm and an approximate sample volume of 7 mL, this glass viscometer is compact yet highly precise.
