Viscometer Provides Consistent Viscosity Measurements

May 22, 2017

KU-3 Krebs Unit Viscometer offers continuous sensing while measuring viscosity in the paints and coatings industry. The ROHS compliant device features a magnetic spindle coupling providing rapid attachment and quick release of the KU spindles. The instrument features a measurement range from 40 to 141 KU, 32 to 1099 gm, and 27 to 5274 cP, accuracy to ±1% of full scale range and reproducibility to ±0.5% of full scale range. Test results can be locked in with hold key.


The updated KU-3 has a new user interface with touch pad control and bright LED display.  A flexible accordion cover protects the lab stand rod. The base plate supports the instrument and has a convenient recess for placement of a quart-size paint can. A single-piece paint can adapter accommodates pint and half-pint cans in the same recess.
