PCE-RVI 5 Krebs Stormer Viscometer / Viscosity Meter

Stormer-type viscometer to measure Krebs Unit (KU) viscosity automatically or manually

PCE-RVI 5 is a Krebs viscometer or Stormer viscometer used in industrial and research applications to measure Krebs Unit viscosity according to

the ASTM D562, ASTM D1131 and ASTM D856 standards. Featuring a unique automatic test mode for reliable, consistently repeatable and

reproducible test results, this Krebs Stormer viscometer displays measurements in Krebs Units (KU), grams (g) and centipoise (cP).

Automatic mode

Place the beaker on a stand on the base and press start. The Krebs spindle will lower to the correct position automatically. The viscometer will

run a fully automated test using shear rate to measure the viscosity of the fluid in the beaker, and the LCD digital display will show the test

results. Upon completion of the test, the Krebs spindle will return to the start position to allow the beaker to be removed.

Manual mode

Manual operation is recommended when testing the viscosity of abnormally sized samples.

Used in the testing, development, manufacture and quality control of paints, coatings, lacquers, varnishes, adhesives, pastes and liquid inks, this

Krebs viscometer:

Includes a bright, easy-to-read LCD digital display

Offers an integrated RS-232 interface or communications port for sending results to a printer

Allows viscosity measurements to be performed automatically or manually

Provides an adjustable running time from 5 to 99 seconds (when automated)

Maintains a constant speed of 200 revolutions per minute (rpm)
