Overview
Product Display Product Application

The VM4000 series viscometer-densimeters employ the vibrating wire method, enabling simultaneous measurement of liquid viscosity and density. They can measure viscosities as low as 0.1 mPa·s and cover a density range of 500~2000 kg/m³, with a temperature measurement range of -30~200 ℃. An optional pressure module allows pressure measurements within 0.1~15 MPa, facilitating the acquisition of viscosity-pressure curves and viscosity-pressure coefficients, as well as the plotting of pVT curves based on viscosity-temperature and viscosity-pressure properties.

These instruments are easy to operate and support automated testing, including automatic temperature control, pressure regulation, and sample injection, significantly reducing labor costs. Additionally, the VM series features a sealed test chamber, which effectively prevents the loss of volatile liquids and ensures the reliability of measurement results.
