Viscosity measurement of coatings is essential at each stage of the manufacturing process to ensure consistent quality standards. Many parameters can affect the rheological behaviour 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+ Viscomixer is a versatile instrument used to measure the change in viscosity during the addition of a solvent or thinner. Three Viscomixer models are available each offering a different measuring range according to the viscosity of the test sample. A sample from a production batch can be quickly and easily measured in a 250ml tin and the required thinning ratio determined for scaling into the production process. The instrument operates at a fixed speed of 562rpm to directly measure the viscosity in Poise (P).
FEATURES
Rhopoint Viscomixer Viscometer ScreenPrecise 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.
Paint Resistant Design
Lab-tough glass allows easy removal and cleaning of unintentional splashes and smears from the capacitive sense buttons and screen.
The solvent resistant anodised aluminium instrument chassis ensures the instrument can be cleaned and restored to pristine condition even in the toughest working environments.Viscometer Printer Label
Data transfer
Measurement data including time, date and test temperature can be printed to a Rhopoint label printer (supplied as an optional accessory).
Printed labels can be attached to each sample for easy identification and recording of results.
Flexible range configuration
The Viscomixer can be configured for any of the three ranges by purchasing an additional paddle for the range required along with a calibration oil kit.
Full details of paddles available along with their respective calibration kits are detailed at the back of the brochure.
Calibration
Annual calibration can be performed remotely by the user using the Rhopoint certified recalibration kit. Step by step instructions and automatic verification ensure accurate, traceable results
