INTRODUCTION
The U.S. Solid Digital Rotational Viscometer measures the viscosity of compatible liquid samples for laboratory testing, production inspection, and routine quality control. Its large LCD screen provides direct readings of viscosity and testing information, while microcomputer control supports stable operation and practical method setup.
With four fixed speeds, standard No. 1 to No. 4 rotors, timed measurement, and automatic scanning assistance, the helps users select suitable test conditions for oils, paints, inks, adhesives, coatings, food products, and other compatible liquid or semi-liquid samples.
Important: Measurement results depend on the selected rotor, speed, sample temperature, and sample properties. For meaningful comparisons, use consistent test conditions and keep torque within the recommended operating range.
FEATURES
- Large LCD Display: Displays viscosity, rotor, speed, and other test information directly for convenient monitoring during measurement.
- 4 Fixed Test Speeds: Select 6, 12, 30, or 60 rpm to establish suitable conditions for compatible liquid samples.
- 1-100,000 mPa·s Range: Covers a broad viscosity range when used with the appropriate standard rotor and speed combination.
- Automatic Scanning Assistance: Automatically scans and recommends a suitable rotor and rotational-speed combination to support initial range selection.
- Timed Measurement: Standard timed-measurement function supports repeatable test procedures and observation of viscosity changes over time.
- Measurement Range Display: Shows the maximum measurable viscosity for the selected rotor and speed combination.
- Data Output Ready: Includes a data output interface. Optional data-processing software and compatible printing accessories are available separately.
APPLICATIONS
- Paints, coatings, inks, and paper pulp
- Adhesives, latex, solvents, and biochemical products
- Cosmetics, creams, lotions, and personal-care formulations
- Food products, starches, sauces, and similar liquid or semi-liquid samples
- Laboratory research, production inspection, and quality-control testing

FAQ
1. How do I select the appropriate rotor and speed?
If the sample viscosity is unknown, begin with a higher-numbered rotor at a low speed, such as the No. 4 rotor at 6 rpm. Adjust the rotor and speed according to the measured torque and the instrument's measurement range table. Higher-viscosity liquids generally require a higher-numbered rotor at a lower speed; lower-viscosity liquids generally require a lower-numbered rotor at a higher speed.
2. Does the USS-DVT01023 measure sample temperature?
A compatible temperature-measurement configuration is available. The temperature probe records sample temperature; it does not heat or cool the sample. Separate temperature-control equipment is required when heating or cooling is needed.
3. How can I help maintain measurement accuracy?
Keep the sample temperature stable, avoid air bubbles, keep the rotor centered in the sample, and use the same rotor, speed, container, and test duration when comparing samples. For Newtonian fluids, the specified measurement error is ±2% of full scale.
4. What is the optional No. 0 rotor used for?
The optional No. 0 rotor is intended for compatible ultra-low-viscosity samples below 10 mPa·s. It is not included with the standard No. 1 to No. 4 rotor configuration unless specifically stated.
5. Can it connect to external accessories?
The instrument includes a data output interface. Optional accessories may include data-processing software, temperature-control equipment, a temperature probe, and compatible printing equipment, depending on the ordered configuration.
