SNB-RH High-Temperature Digital Viscometer
The SNB-RH is designed for viscosity measurement of materials that require heating before testing, especially samples that are solid or highly viscous at room temperature and become fluid at elevated temperatures. Its integrated heating furnace provides a controlled high-temperature measurement environment with direct LCD display of key test data.
- Viscosity Range：50–200,000 mPa·s
- Temperature Control：Up to 300°C
- Rotational Speeds: 5/10/20/50/100 RPM
- Sample Volume：10–20 mL
- Accuracy in Use：±1% Full Scale
Features of SNB-RH Digital Viscometer
- The main measurement is solid at room temperature and liquid after high temperature heating, such as asphalt, hot melt adhesive, polyethylene wax and so on.
- The measured data can be displayed directly on the LCD screen without secondary calculation. < VSoft Viscometer Data Collection,Analysis and Graphing Software > can also be selected to realize data acquisition and analysis and to compile the viscosity-temperature curve.
- High subdivision stepper motor, accurate and stable speed.
- LCD liquid crystal with blue backlight function can directly display the viscosity, speed, percentile torque, spindle number and the maximum viscosity and temperature of the selected spindle at the current speed. Viscosity value shows continuous change, beyond the measurement range there is an alarm sound prompt.
- The measuring performance of the instrument has reached the level of the same type of products abroad through computer correction accuracy.
- High-temperature furnace uses embedded integral heating, uniform heating and small thermal inertia.
What Can the SNB-RH High-Temperature Digital Viscometer Measure?
How to Operate High-Temperature Digital Viscometer?
1. Prepare the Sample
Place approximately 10–20 mL of sample into the high-temperature sample container.
2. Set the Test Temperature
Heat the sample to the required measurement temperature.
3. Select Spindle and Speed
Install a suitable spindle and set the rotational speed according to the expected viscosity.
4. Allow the Reading to Stabilize
Confirm that temperature and viscosity readings have stabilized before recording the result.
5. Record or Export Data
Read the result directly from the display or use optional VSoft software for data collection and viscosity–temperature analysis.
