CANNON 9721-K86 Ubbelohde 650 Calibrated

The CANNON 9721-K86 Ubbelohde 650 Calibrated is a high-precision suspended-level viscometer developed for accurate measurement of kinematic viscosity in transparent Newtonian liquids. This instrument complies with ASTM D445 and ISO 3104, ensuring standardized and reproducible viscosity testing for professional laboratory applications. Therefore, it is ideal for facilities that require dependable results across a wide temperature range.

Product Features

First, the Ubbelohde suspended-level design maintains a constant hydrostatic head during measurement. As a result, no kinetic energy correction is required within the extensive viscosity range of 0.5 to 100,000 centistokes. In addition, the viscometer performs effectively at temperatures above 93 °C (200 °F) and below −18 °C (0 °F). Consequently, it is well suited for demanding high-temperature and low-temperature testing environments.

Moreover, this model is calibrated at 40 °C and supplied with a certificate of calibration and an instruction sheet. The viscometer constant remains the same at all temperatures, ensuring stable and accurate performance under varying test conditions. Furthermore, its specifications conform to ASTM D446 and ISO 3105, providing traceable and internationally recognized testing standards.

Specifications

The approximate viscometer constant is 45 cSt/s. Therefore, it measures viscosity within a range of 9000 to 45000 cSt, corresponding to flow times between 200 and 1000 seconds. The minimum required sample volume is 11 mL. Additionally, a minimum bath depth of 254 mm (10 inches) is required, and the viscometer must be submerged to 220 mm (8.5 inches) during operation to ensure accurate and consistent results.

Please note that the holder is sold separately. Compatible holder models include 9726-M70, 9726-M73, and 9726-M76.

Applications

This viscometer is widely used in research laboratories, quality control departments, and industrial testing facilities. It is particularly suitable for evaluating jet fuels, hydraulic lubricants, specialty oils, and other transparent Newtonian liquids. In addition, it supports viscosity testing under extreme temperature conditions, making it ideal for petrochemical, aerospace, chemical, and energy industries.
