U-Visc kinematic viscometer

Part Number: U-Visc

The U‑Visc series are fully‑automatic Ubbelohde‑tube viscometers, designed for rapid, unattended kinematic viscosity measurement of Newtonian fluids (lubricants, fuels, polymers), with full ASTM D445/D446 compliance. They offer bath-based thermal control, optical/thermal detection, and are available in 1‑ or 2‑bath configurations with 1 or 2 tubes per bath.
The BitUVisc variant extends the viscosity range up to 120,000 mm²/s and allows measurements up to 150 °C, ideal for high-viscosity samples .
