About this product

Microprocessor PID speed control keeps rpm accurate and stable under load, while an anti-spill slow start ramps speed gradually to reduce splashing and foam formation. An LCD shows set and actual speed and torque in real time, over-torque protection automatically stops the motor, and an RS232 interface enables PC control and documentation of measured values.

  • 10K to 50K cPsMaximum viscosity
  • 20 to 40 LMaximum stirring volume
  • 32.25 inIncluded stand height
  • 5/8 inStand rod diameter
  • Stable PID speed. Microprocessor PID ensures accurate, stable rpm under load.
  • Anti-spill start. Slow start ramps speed gradually to reduce splashing and foam.
  • Real-time monitoring. LCD shows set and actual values for speed and torque.
  • Over-torque protection. Motor stops automatically when torque limits are exceeded.
  • PC connectivity. RS232 interface for PC control and speed/torque documentation.

Applications: Chemical synthesis, Pharmaceutical & biotech, Academic & research, Process development
