The Digital Rotothinner™ DV2700 is used to measure the viscosity of paint, coatings and inks in P or cP units. We developed this industry-leading Rotothinner viscometer for highly reproducible results and insightful stability analysis.
Developed by TQC Sheen, our paint testing specialist brand, the Digital Rotothinner™ DV2700 has a flexibility that gives you the ultimate control during the viscosity reduction process.
Fluid viscosity testing is essential when you need to check whether your paints, coatings, and varnishes are suitably resistant to flow or deformation.
The Sheen Rotothinner viscosity tester is highly accurate and simple to use in a research setting or within a production environment. Our reliable viscosity tester is equipped with a digital display and an easy user interface.
When you make the wise decision to purchase a Sheen Rotothinner™ then you get:
When you purchase our Rotothinner viscometer you get three measuring ranges in one instrument. The Sheen Rotothinner can be supplied with a choice of the following plate and ball spindles:
The Sheen Rotothinner also has three separate modes: manual, maxhold and timed.
The Sheen Rotothinner™ lets you easily monitor a sample material’s viscosity during the addition of solvents and thinners to create supply or RFU viscosity.
Our Rotothinner viscometer is set up for definitive viscosity analysis at times you preselect. This gives you excellent data relating to shear performance and stability analysis. It also makes the Sheen Rotothinner perfect for laboratory or factory applications.
A superb stable drive system creates a wider measurement range and more accurate readings using the Sheen Rotothinner, compared to the competition.
It’s a simple enough process to generate a highly accurate fluid viscosity measurement using our Rotothinner viscometer.
First up you fill a container with sample fluid which is positioned on a magnetic ring mounted on top of the base.
Next you submerse the spindle in the sample fluid by lowering the handle. At the lowest point the spindle starts rotating with a set constant speed.
The display quickly and easily shows the actual fluid viscosity measurement in poise. If you need a measurement from a more structured material then it takes a little longer as the spindle applies shear. This influences the reading and it’s the reason for the reading presets the Sheen Rotothinner offers..
The Sheen Rotothinner is easy to clean and maintain. ‘Spin off’ and retain the sample material after taking your readings. Use the quick release chuck to swap spindles effortlessly.
The Sheen Rotothinner is microprocessor-controlled for accuracy and repeatability. The accuracy is enhanced by the automatic multi-point calibration.
Our Sheen Rotothinner will help you to carry out viscosity testing to the most stringent of international standards, including:
In the Industrial Physics portfolio we have lots of different devices that are designed for all types of viscosity testing applications.
The TQC Sheen Coatmaster Flex measures coating thickness immediately after application. You can rely upon the Coatmaster Flex for measuring wet and cured/dried powders and paints.
Our TQC Sheen Viscosity Cups are made of titanium anodised aluminum and have a fixed nozzle. These immersion ford cups are designed to support your testing to international standards, including ASTM D1200.
We’ve learnt a thing or two about best practice when it comes to taking fluid viscosity measurements to international standards over the years. We share some of this insight with our customers through the knowledgebase of this website.
Here you’ll find some of the blogs we have published, like this one – which looks at how to measure viscosity. Then, perhaps follow up with this piece exploring cost savings via viscosity management in paper and board coating.

When your customers must be able to rely on your inks and coatings there’s no margin for error in your test and inspection processes. So, settling for second-rate equipment and advice is a risky business!
With several dedicated inks and coatings testing brands in the Industrial Physics family, our industry-leading product portfolio and expertise is even relied upon by leading paint testing laboratories.
Artur Palasz, R&D Director at Spektrochem, said:
“Many of our customers appreciate Industrial Physics equipment, because it is a world-class apparatus that they know and use in their laboratories. Excellent technical contact, perfect customer service and fast order processing time are undoubtedly additional advantages that determine the choice of Industrial Physics as our permanent supplier of laboratory equipment today and in the future.”
