Fast-run viscometer tubes
CANNON
®
Instrument Company has developed a fast-run viscometer
tube for the CAV. Results of viscosity measurements are typically avail-
able within 3-5 minutes. The fast-run tube has a tenfold range (i.e., 60-
600 cSt), and requires less sample volume for testing (12-17 ml) and less
solvent for cleaning than the standard CAV tube. Fast-run tubes may be
used for most typical CAV applications and are ideally suited for analyz-
ing used oils.
Fast-run viscometer tubes are available upon request, either at the time of
your initial CAV purchase, or as a future upgrade.
Temperature bath
The temperature bath is capable of maintaining constant temperatures
between 20°C and 100°C (150°C for high-temperature bath models).
Silicone bath fluid is circulated via a pump or central stirring rod. The bath
also stainless steel resistance heating elements. Solid state temperature
control circuits provide proportional control with reset. Thermal fuses are
installed to protect all heating elements.
Bath fluid grades
The temperature bath is ordinarily filled with Dow Corning 200 silicone
fluid, supplied by CANNON
®
Instrument Company. The viscosity of the
fluid depends upon the temperature of the bath during most operations:

Expansion vessel (CAV-2100 only)
The CAV-2100 expansion vessel has been designed to hold excess liquid
when the CAV is operating at high bath temperatures. The expansion
