Viscometer - Viscosity Baths

Viscosity baths for use with glass capillary viscometers must be extremely accurate. A tolerance of +/- 0.02 degrees C is allowed in the interval 0-100 degrees C. The new EVS Viscometer Bath from PSL Rheotek is accurate to +/- 0.005 degrees C and exceeds the ASTM requirement.
Most commercial baths claim accuracy to +/- 0.01 degrees C but traceability on the documentation behind this claim is not always easy to find. The laboratory at PSL Rheotek in Essex is UKAS accredited for temperature calibration and holds a temperature reference. Documentation for all claims available on request.
