ViscoPro 2100

In-Line Viscometer for the Process Industry


ViscoPro 2100 Viscometers are Designed to Handle the Challenges of Process Environments

Cambridge Viscosity’s ViscoPro 2100 is designed to stand up to the challenges within the process industry. With a sensor that is designed to protect itself from outside elements, the ViscoPro 2100 is highly insensitive to the outside environment. Its continuous piston motion means that the VP2100 is self-cleaning and can run for years without recalibration.
