For oils, lubricants and many formulations, behavior at low temperature is what separates a working product from a failed one. As fluids cool, viscosity can climb by orders of magnitude — and the shape of that rise is what engineers need to design around.

A controlled sweep

The viscometer sits in an engineered thermal jacket fed by a circulating bath. Temperature is driven smoothly from −30 °C to +40 °C while the piston sensor reads continuously, so the entire cold-flow curve is captured in one automated run.

Four ranges, one cell

Interchangeable pistons let a single instrument span 0.1 to 20,000 cP, so a fluid that thickens dramatically on cooling stays in range from start to finish.
