Cannon®-Fenske Opaque Reverse Flow
Viscometers
The reverse flow viscometers are designed for
testing opaque liquids. These viscometers wet
the timing section of the viscometer capillary
only during the actual measurement and must
be cleaned, dried and refilled before a repeat
measurement can be made. By contrast, other
viscometer types commonly used to measure
transparent liquids allow the sample to be
repeatedly drawn up into the capillary, permitting
duplicate measurements.

For measurement of transparent and dark
liquids having kinematic viscosities of up
to 20,000cSt

Requires a sample of approx 12mL.

Can be used for viscosities of asphalts by
ASTM D2170 method.

Ubbelohde
Ubbelohde viscometers measure transparent
liquids, and unlike the Cannon
®
-Fenske Routine
viscometers, they maintain the same viscometer
constant
at all temperatures. This is
advantageous when samples are to be
measured at different temperatures.

Suspended-level type viscometers are for
transparent liquids of up to 100,000cSt

Requires a sample volume of approx
11mL.

Viscometer Holders
To perform viscosity measurements, Koehler
offers viscometer holders for use with the
KV4000. The correct holder must be used with
the corresponding viscometer tube for proper
operation:
