Thomas®-Stormer® Viscosity Standards
 
Thomas-Stormer viscosity standards calibrate manual and electronic Thomas-Stormer viscometers. The KREBS UNIT (KU) is often used for Thomas-Stormer viscometers. Lot specific viscosity data (in cP and KU) is provided with each standard at 23 °C, 24 °C, 24.5 °C, 25 °C, 25.5 °C and 26 °C.
