The Velp® OHS Digital overhead stirrer is perfect for your medium to high viscous applications. Mix up to 100 L of fluid at once while maintaining full control. One rpm accuracy ensures maximum reproducibility. The electronic-controlled brushless DC motor is silent even at maximum operating speed while ensuring stable torque through the whole speed range allowing for peaceful use. The SpeedServo™ torque compensation maintains a constant speed, automatically adjusting to viscosity changes.

The compact IP54-rated mixer features an extremely resistant sealed case for a long lifespan and dependability while maintaining your safety. There is also full protection in case of overload, overtemperature, and over current for unattended work. The lock key prevents unintentional changes of the work setting.

SmartChuck™ allows you to easily change the shaft with just one hand to accommodate a variety of applications—no tools needed. The mixer accepts a chuck with diameter from 1 to 13 mm.

The LED display shows the real-time torque as the viscosity of your sample changes. The screen allows you to view the time you set, speed, and torque. A timer is integrated for unattended operation with an automatic switch off. Conveniently view the timer on the display while not worrying about constantly attending the mixer.
