Rhopoint Krebs Viscometer

Viscosity measurement of coatings is essential at each stage of the manufacturing process to ensure consistent quality standards.

Krebs Unit Viscometer Model KU-2

Many parameters can affect the rheological behavior of a finished coating resulting in undesirable effects such as inconsistent performance, poor levelling or sagging. The use of high precision measuring instruments is therefore essential in quality control to prevent such problems occurring during formulation, manufacture and application.

The PAINTLAB+ Krebs Viscometer Instruments offers high accuracy viscosity measurement with advanced functionality. Based on the standard ASTM Krebs test method, the viscometer uses a rotating paddle at a fixed speed of 200rpm to directly measure the viscosity in Krebs units (KU), centipoise (cP) or grams (g).




Precise Measurement
High stability motor speed control ensures accuracy and repeatabilty during each test. Real-time high resolution graphing allows monitoring of changes during measurement providing identification of inconsistencies between samples. Measurement results are displayed instantly on screen after test in all three units.
Advanced Temperature Monitoring
An integrated temperature probe accurately measures and records sample temperature for each test. As sample viscosity is influenced by test temperature, accurate monitoring and recording ensures reliability of test results.
Automatic Operation
Fully automated operation saves time by accurately lowering the paddle into the sample to the correct height for a number of standard container sizes. Once the test has completed the paddle automatically raises to drain off, saving time during cleaning. The easy to use quick release magnetic paddle holder allows rapid removal for cleaning after use.

Easy Clean Design
Lab-tough glass allows easy removal and cleaning of unintentional splashes and smears from the capacitive sense buttons and screen. The solvent resistant anodized aluminium instrument chassis ensures the instrument can be cleaned and restored to pristine condition even in the toughest working environments.

Easy Clean Design
Data Transfer
Measurement data including time, date and test temperature can be printed to a label printer (supplied as an optional accessory). Printed labels can be attached to each sample for easy identification and recording of results. Measurement data can also be transferred directly into Excel using the optional data transfer cable
Annual calibration can be performed remotely by the user using the certified recalibration kit. (Supplied as optional accessory) Step by step instructions and automatic verification ensure accurate, traceable results.
