Stormer-Type Viscometer - Digital KU-2

Stormer-Type Viscometer - Digital KU-2

Conforms to ASTM D 562

The Stormer-Type Viscometer - Digital KU-2 provides a direct digital reading in Krebs units (KU), centipoise, and grams (gm). This simplifies an established test procedure providing an immediate calculation of the viscosity value. The viscometer automatically starts or stops by lowering or raising the viscometer. The KU-2 automatically establishes the correct rotational speed to comply with ASTM method D 562.

  • Easy to use – no weights or stroboscopic timing attachment
  • Switch selectable LED digital display of Krebs units or grams or centipoise
  • Allows for rapid and easy measurement of samples
  • Parallel printer output for test documentation
  • Instrument base fits standard pint, 1/2 pint and quart cans
  • Traceable to NIST

The Stormer-Type Viscometer - Digital KU-2 can be equipped with an air purge that allows the interior of the instrument to be pressurized with air or inert gas. Recommended when working in a hazardous environment.
