TQC Sheen Digital Rotothinner™ DV2700

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.  

What’s in the Sheen Rotothinner toolbox?

When you make the wise decision to purchase a Sheen Rotothinner™ then you get:

• DV2700 – Sheen Rotothinner 
• 240V/110V power adapter 
• User manual 
• Calibration certificate included 
• Handle

Triple fluid viscosity measurements  

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:  

• Plate spindles are used for fluid viscosity measurement of fluids of 0-22 poise 
• Large ball spindles are used for fluid viscosity measurements of fluids between 0-75 poise 
• Small ball spindles are used for fluid viscosity measurements of fluids between 0-350 poise

The Sheen Rotothinner also has three separate modes: manual, maxhold and timed.  

Continuous fluid viscosity measurement

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.  

Time-controlled fluid viscosity measurement  

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. 

Strong and stable fluid viscosity measurement

A superb stable drive system creates a wider measurement range and more accurate readings using the Sheen Rotothinner, compared to the competition.  

How does the Sheen Rotothinner work? 

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.. 

Easy clean fluid viscosity measurement  

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.  

Accurate and repeatable fluid viscosity measurement

The Sheen Rotothinner is microprocessor-controlled for accuracy and repeatability. The accuracy is enhanced by the automatic multi-point calibration.  

Multi-sector fluid viscosity measurement  

The Sheen Rotothinner is relied upon by our customers across many industries including automotive, inks and coatings, construction and civil engineering and metal packaging. 

Fluid viscosity measurement to international standards

Our Sheen Rotothinner will help you to carry out viscosity testing to the most stringent of international standards, including: 

• BS 3900-A7  
• ISO 2884-2

Viscosity testing product portfolio

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.  

Our testing knowledge is hard to beat!

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. 

Finally, while we’re on the subject of viscosity testing, here’s a couple of handy tools: the TQC Sheen Viscosity Calculator and also our viscosity conversion table.
