CANNON glass capillary viscometers are engineered to deliver reliable and accurate viscosity testing across a wide range of laboratory applications. Each viscometer is traceable to NIST calibration standards and manufactured in an ISO 9001-registered, A2LA-accredited facility to ensure consistent quality, repeatability, and compliance.

Since 1938, CANNON Instrument Company has been producing glass capillary viscometers for petroleum, polymer, chemical, pharmaceutical, and research laboratories worldwide. Because different samples and testing conditions require different viscometer designs, CANNON offers a broad selection of glass capillary viscometers to support both routine testing and specialized research applications.

Transparent viscometers are designed for transparent and translucent liquids, providing accurate kinematic viscosity measurement for a variety of laboratory samples.

Suspended Level viscometers are also used for transparent and translucent liquids and are especially useful for testing at multiple temperatures because they maintain the same viscometer constant across all temperatures.

Dilution viscometers are developed for polymer solution testing, allowing controlled dilution to estimate molecular size and shape.

Reverse Flow viscometers are suitable for both transparent and opaque liquids. These viscometers require cleaning, drying, and refilling between repeat determinations to maintain accuracy.

Vacuum viscometers are a specialized type of reverse-flow viscometer used for highly viscous transparent or opaque samples. These systems require accurately controlled vacuum conditions to pull the sample through the viscometer for precise measurement.

Labindia Instruments is the authorised distributor of CANNON Instrument Company in India, providing sales, application support, installation, and after-sales service for advanced viscosity testing solutions across petroleum, polymer, pharmaceutical, chemical, and industrial laboratories.

ASTM D445, ISO 3104
The BS/U-Tube Viscometer measures kinematic viscosity of transparent Newtonian liquids according to ASTM D445 and ISO 3104.
Please refer to the details mentioned in the attached catalogue.

CANNON-Fenske Opaque Viscometer (Reversed Flow)

ASTM D445, ASTM D2170, ISO 3104
The Cannon-Fenske Opaque Viscometer is a reverse-flow type, for measurement of kinematic viscosity of dark Newtonian liquids according to ASTM D445 and ISO 3104. It permits measurement of liquids whose meniscus cannot be seen at the timing marks when using a Cannon-Fenske Routine-type viscometer. Used to measure kinematic viscosity of liquid (cutback) asphalts and road oils

Cannon-Manning Vacuum Viscometer (Reversed Flow)

ASTM D2171
The Cannon-Manning Vacuum Viscometer measures the viscosity of highly viscous materials according to ASTM D2171. Minimum sample volume is 6 mL. Minimum bath depth is 180 mm (7.1 in).
Please refer to the details mentioned in the attached catalogue.

ASTM D445, ISO 3104
The BS/IP/SL Suspended Level Viscometer measures kinematic viscosity of transparent Newtonian liquids according to ASTM D445 and ISO 3104. Please refer to the details mentioned in the attached catalogue.

CFRC - CANNON - Fenske Routine Viscometer

ASTM D445, ASTM D2170, ISO 3104
The Cannon-Fenske Routine Viscometer measures kinematic viscosity of transparent Newtonian liquids, particularly petroleum products or lubricants, according to ASTM D445 and ISO 3104.

ASTM D445, ISO 3104
The Cannon-Ubbelohde Viscometer, with a more rugged design than standard Ubbelohde viscometers, is a suspended level viscometer 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.
