Cannon Fenske Opaque Viscometers

The Cannon Fenske Opaque is a popular reverse flow viscometer that has two separate timing bulbs allowing a check of results in the same test. It requires a minimum bath depth of 10 inches and a sample of 12mL. Each viscometer has a permanent serial number and is supplied with a calibration certificate indicating the constant of that tube at 40°C and 100°C. Recertification available.
