Viscosity Standards for Cone/Plate, Stormer Rotothinner and all other Viscometers

The Quality Control Laboratory has developed with Cannon Instruments a unique listing of Calibration Standards. These standards are calibrated over 6 temperatures from 20 degrees Centigrade to 27.0 Centigrade. These oils are now packaged so they can be used for any Viscometer.

The following table related to a direct comparison to calibration oils supplied by The Paint Research AssociationPRA ).

Note: P.R.A. calibration oils are accurate to no better then plus or minus 1% at best. The following oils have an accuracy of +/- 0.2%.

Viscosity standards are based on the National bureau of Standards value of 1.002 centipoise for water at 20 degrees Centigrade. All Standards are traceable to the National Bureau of Standards ( NBS ) / National Institute of Standards and Technology ( NIST ).

Calibration Kits For Cone & Plate Viscometers Comprising:

Kit 1 – Contains 1, 3, 5, 7 POISE

Kit 2 – Contains 5, 7, 10, 25 POISE

Kit 3 – Contains any 4 from above Kit 1 & 2

Enables end user to calibrate using small samples at a low cost. ( Supplied with certification )

These standards can also be used for other Cones & Plates ( i.e. Brookfield and Haake ).
