For measuring kinematic viscosity of transparent Newtonian liquids, particularly petroleum products or lubricants, according to ASTM D 445 and ISO 3104. These tubes are factory calibrated. Specifications conform to ASTM D 446 and ISO 3105. Approximately 7 mL of sample is needed. If you are measuring liquids whose meniscus cannot be seen at the timing marks, use the Cannon-Fenske Opaque type viscometer.

Reverse-flow type, for measurement of kinematic viscosity of dark Newtonian liquids according to ASTM D 445 and ISO 3104. Permit measurements of liquids whose meniscus cannot be seen at the timing marks when using a Cannon-Fenske Routine type viscometer. Factory calibration certificate is supplied. Requires minimum sample volume of 12mL. Used to measure kinematic viscosity of liquid (cutback) asphalts and road oils at 60°C (140°F) in range of 30 to 6000 centistokes according to ASTM D 2170.

Cannon®-Manning Vacuum Viscosity Tubes are for measurement of viscosity of highly viscous materials such as asphalt cement at 60°C (140°F) according to ASTM D 2171. Applicable to materials with viscosity range of 0.036 to 80 000 poise. Vacuum of 300 mm Hg is applied to small arm with timing bulbs; two bulbs are incorporated to extend viscosity range of viscometer. Provided with certificate of calibration. Minimum sample volume 6 mL. Require liquid bath depth of 180 mm (7.1").

These silicone bath oils are clear, colorless liquids that can be used as heat transfer media in CANNON automated viscometers and some high-temperature CANNON baths where IBF fluid (see below) is not effective. Three viscosity grades of silicone bath fluid are available for different temperature/viscosity ranges (see order information below).

Please note: In CANNON Automatic Viscometer baths, the following silicone oils are recommended: 9726-L30 for use from 25 to 100°C, 9726-L33 for use from 80 to 135°C, 9726-L36 for use from 135 to 150°C.

Suspended level (Cannon Ubbelohde) viscometers are used for measurement of kinematic viscosity of transparent Newtonian liquids according to ASTM D 445 and ISO 3104. Also used for evaluating jet and hydraulic lubricants. Especially suited for use at temperatures above 93°C (200°F) or below -18°C (0°F). Require no kinetic energy corrections over 0.5 to 100 000 centistokes range. Viscometer constant is same at all temperatures. Specifications conform to ASTM D 446 and ISO 3105. Minimum sample volume is 11mL.

For measurement of kinematic viscosity of transparent and opaque Newtonian liquids according to ASTM D445 and ISO 3104. Specifications conform to ASTM D446 and ISO 3105. Also used to measure kinematic viscosity of liquid (cutback) asphalts and road oils at 60°C (140°F) and asphalt cements at 135°C (275°F) in the range of 30 to 6000 centistokes according to ASTM D2170. Can be filled and cleaned while in constant temperature bath. Provided with certificate of calibration. Minimum sample volume is 1 to 3 mL. Requires liquid bath depth of 230 mm (9").
