For oils, lubricants and many formulations, behavior at low temperature 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 exactly what cold-climate performance depends on.

A controlled sweep

The viscometer sits in an engineered thermal jacket fed by a circulating bath. Temperature is driven smoothly down to −30 °C while the piston sensor reads continuously, so the entire cold-flow curve is captured — useful context alongside single-point ASTM D2983 Brookfield results.

Four ranges, one cell

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