High-temperature Viscometer BDV-1H / BDV-1HB / BDV-1L / BDV-2H / BDV-2HB / BDV-2L (CAT#: STEM-OEM-0300-ZJF)

This high-temperature viscometer is specifically designed to measure materials that are solid at room temperature and become liquid when heated, such as asphalt, hot melt adhesives, and polyethylene wax. Engineered to withstand and precisely evaluate the flow properties of fluids at elevated temperatures, it is ideal for applications requiring viscosity analysis up to several hundred degrees Celsius.

Displays real-time viscosity data directly on the LCD screen, no secondary calculation needed; optional VSoft software enables data collection, analysis, and viscosity-temperature curve plotting.
Equipped with high subdivision stepper motor for precise and stable speed control.
Blue-backlit LCD shows viscosity, speed, torque %, spindle number, maximum viscosity, and temperature; BDV-2 also displays shear rate and shear stress with audible alert when beyond measurement range.
High-temperature furnace adopts embedded integral heating for uniform heat distribution and low thermal inertia.
