Automated Kinematic Viscometer (AKV-diesel)

Key features include:

• Fully complies with ASTM D445
• Two measuring positions
• Easy sample filling - remove cap and pour in sample
• Precise ASTM Ubbelohde viscometer tubes with ISO 17025 calibration certificates
• In situ solvent cleaning and drying
• User friendly PC control system

Advantages:

• Modular, price competitive system
• Two measuring positions
• Independent calibration of standard ASTM Ubbelohde tubes - avoids "in-situ" calibration errors, as well as calibration traceability
• Mini pumps are used to push the sample up the capillary. (This avoids possible light ends loss under vacuum, as well as protecting the valve system from solvent fumes)
• Fast flow times permitted for automated viscometer
• In situ cleaning, including the use of acetone for drying
• Almost unlimited database of results
• Expansion options as well as XYZ auto sampler  

The RHEOTEK AKV-diesel provides a reliable and precise method for measuring gas oils, distillate fuels and diesels at 40 deg. C.

Automatic flow time measurements are determined in high precision ASTM Ubbelohde viscometer tubes.

Reported kinematic viscosity results are in full compliance with ASTM D455, IP 71 & ISO 3104.

The AKV-diesel system is truly compliant with ASTM D445 – using standard apparatus and automating the manual steps set out in the method.

Furthermore, independent calibration provides the lowest possible uncertainties of measurement.

The AKV system is suitable for other applications, including biodiesels.
