JFDVT01 Series: U.S. Solid’s Next-Generation Touchscreen Rotary Viscometers
When viscosity control matters, the right instrument can make daily testing faster, more accurate, and more repeatable. The U.S. Solid JFDVT01 Series Rotary Viscometers are designed as an upgraded touchscreen solution for laboratories, manufacturers, and quality control teams that need precise viscosity measurement with easier operation and better data handling.
Compared with classic LCD rotary viscometers, the JFDVT01 series offers a more modern interface, higher accuracy, finer speed control, and smarter test setup features.
A Smarter Way to Measure Viscosity
The JFDVT01 series replaces traditional button-based operation with a 5-inch full-color touchscreen. Built on an ARM + Linux system, the interface is clear, responsive, and easy to navigate, allowing users to set parameters, run tests, view curves, save records, and export data more efficiently.
Each model in the DVT01 series is built for professional viscosity testing and includes the following key advantages:
- ±1% measurement accuracy for Newtonian fluids, offering higher precision than classic ±2% LCD models
- 0.1-200 rpm stepless speed control with up to 2,000 selectable speed steps for fine adjustment across different sample types
- Auto Scan function to help recommend a suitable rotor and speed combination when the sample viscosity is unknown
- Real-time curve display for visualizing viscosity changes during testing
- Stored test conditions for repeatable workflows and faster setup
- USB data export for convenient backup of stored test records
- RS232 interface for external data communication or printer connection
- 5-inch color touchscreen for clearer operation and easier parameter setting
- Wide voltage input: AC 100-240V, 50/60Hz, suitable for different power environments
Auto Scan: Faster Rotor and Speed Selection
Choosing the right rotor and speed is one of the most important steps in viscosity testing. If the wrong combination is used, the torque may be too high or too low, affecting the reliability of the result.
The JFDVT01 series includes an Auto Scan function that helps simplify this process. Users can enter the scanning interface, install the selected rotor, and start scanning. When the scan result meets the testing requirement, the instrument can apply the recommended rotor and speed settings directly to the test parameters.
This is especially useful when measuring a new or unfamiliar sample.
Designed for Repeatable Testing
For quality control teams, repeatability matters just as much as accuracy. The DVT01 series allows users to save test conditions and recall them later, helping standardize routine measurements.
This makes the instrument well suited for production environments where the same material needs to be checked repeatedly under consistent conditions.
Easy Data Management
After testing, results can be saved in the instrument memory. Users can export stored test data to a USB flash drive, making it easy to back up records or transfer data without extra software.
The instrument also supports external printing or data communication through its interface, helping users document test results more efficiently.
Built for Real-World Applications
The JFDVT01 series can be used across a wide range of industries, including:
- Paints and coatings: monitor flow and application consistency
- Food and beverage: test sauces, syrups, dairy products, and other liquid foods
- Pharmaceuticals: quality control for creams, gels, and liquid medicines
- Adhesives and sealants: evaluate workability and bonding performance
- Petroleum and lubricants: characterize oils, greases, and additives
- Cosmetics: test lotions, creams, foundations, and hair care products
- Polymers and resins: monitor viscosity during formulation and production
Choosing the Right DVT01 Model
| Model | Measuring Range | Best For |
|---|---|---|
| USS-DVT01001 | 1-6,000,000 mPa·s | Low to medium viscosity samples |
| USS-DVT01003 | 100-40,000,000 mPa·s | Medium to high viscosity samples |
| USS-DVT01005 | 200-80,000,000 mPa·s | High viscosity samples |
If your sample viscosity is unknown, start with the Auto Scan function or follow the general testing principle: use a smaller rotor and lower speed for high-viscosity samples, and a larger rotor with higher speed for low-viscosity samples.

Tips for Better Measurement Results
To get accurate and repeatable results:
- Level the instrument before testing.
- Select the correct rotor and speed, or use Auto Scan when unsure.
- Keep the sample temperature stable, since viscosity is highly temperature-sensitive.
- Make sure the rotor is fully immersed and centered in the sample.
- Avoid air bubbles in the test sample.
- Clean the rotor after each use with a suitable solvent.
- Save and export test data regularly for recordkeeping.
Upgrade Your Viscosity Testing Workflow
The U.S. Solid JFDVT01 Series combines touchscreen operation, higher accuracy, stepless speed control, Auto Scan, curve display, and convenient USB data export in one professional instrument.
For users upgrading from classic LCD rotary viscometers, the DVT01 series provides a clear improvement in ease of use, testing flexibility, and measurement efficiency.
