Ravenfield BS/C+ HTHS Tapered Plug Viscometer

The Ravenfield® by CANNON® HTHS BS/C+ Viscometer is a compact, high precision, tapered plug viscometer that measures the high temperature, high shear viscosity of engine lubricants and other oils according to ASTM D4741, CEC L-36-A-90 and IP 370 as specified by SAE J300 and ACEA. The BS/C+ HTHS Tapered Plug Viscometer also correlates to ASTM D4683 with no bias and is capable of testing across a wide range of temperatures and shear rates.

TESC - Thermoelectric Sample Conditioner System

For Low Temperature Viscosity of Lubricants
Automated ASTM D2983

The compact, economical TESC (thermoelectric sample conditioner) system integrates and automates the entire ASTM D2983 conditioning and testing process for low temperature viscosity of gear oils and ATF.


The CANNON CT-1000 Constant Temperature Bath maintains the accurate control required by ASTM D 445 for kinematic viscosity measurements with glass capillary viscometers. Within the range of 20 to 100°C temperature is controlled to 0.01°C; above 100°C temperature is controlled to 0.03°C. The bath chamber is a cylindrical clear Pyrex® vessel 300 mm (12 inches) in diameter x 300 mm (12 inches) high. A stainless steel baffle is located in the center of the bath to provide a good background for viewing viscometers. Two fluorescent lamps illuminate the interior of the bath brightly and uniformly, without glare. Two heating elements inside the bath rapidly heat the bath medium to any temperature within the bath range. A stainless steel cooling coil is also incorporated. When connected to tap water or a recirculating water chiller, the cooling coil allows operation at temperatures slightly above or below ambient.

HTHS : High-Temperature High-Shear Viscometers

The CANNON® High-Temperature High-Shear Capillary Viscometer (HTHS Series II) is designed to determine the viscosity of engine oils and other oils under conditions of high shear at high temperatures. The HTHS is capable of testing at 1.4 x 106s-1 at 150°C and meets all precision specifications of ASTM D 5481 and SAE J300. The Series II design incorporates simple one-button operation - just load samples, set pressure, and press the Start button. If desired, variable shear rates (± 30 percent of the shear rate specified in ASTM D 5481) may be obtained by altering the test pressure (variable from 75 to 500 psi). The viscosity range of 2-7 mPa.s can be extended to more than 20 mPa.s with custom configuration

CANNON CAV® 2000 Series Automatic Viscometers

The CANNON 2000 Series automatic viscometers are benchtop versions of the original CANNON Automatic Viscometer (CAV), the world's leading automatic viscometer for nearly 30 years, used by most major companies in the petroleum industry. 2000 Series instruments are now available in two models. The CAV-2100® features a single-bath modular construction with two viscometers per bath. The CAV-2200® features a dual-bath modular construction with a single viscometer in each bath.

Glass Capillary Viscometers

• The Cannon-Fenske Routine viscometer is a rugged and inexpensive viscometer that works well if the liquid to be measured is transparent or translucent

• The Ubbelohde viscometer and other suspended level viscometers are also used to measure transparent liquids. Unlike the Cannon-Fenske Routine viscometer, suspended level viscometers possess the same viscometer constant at all temperatures.

• Special reverse flow viscometers have been designed for testing opaque liquids. Reverse flow viscometers wet the timing section of the viscometer capillary only during the actual measurement. The Cannon-Fenske Opaque, Zeitfuchs Cross-Arm, and BS/IP/RF U-Tube viscometers are all reverse flow types

• When liquids are too viscous to flow readily under gravity, vacuum viscometers may be used to measure viscosity (in mPa.s or cP). In these instruments a vacuum is applied to one end of the viscometer to pull the liquid through the capillary into the timing bulb(s). CANNON offers several types of vacuum viscometers, including the Cannon-Manning Vacuum, the Asphalt Institute Vacuum, and the Modified Koppers Vacuum.
