The top of the ladder: 50 and 100 liters

The OS-50Pro states 50 L, 50 N·cm and 35,000 mPa·s reaching 2000 rpm; the OS-100Pro, 100 L, 100 N·cm and 70,000 mPa·s at 50-1200 rpm — double the torque and viscosity, prioritized over speed.

The high-end sensors

Only this family states a temperature and torque display, tip-over detection and one-click lock, with a paddle pass-through hole and 80 or 100 W.
