It simultaneously measures liquid viscosity and density, with a temperature range from RT+10°C to 200°C, suitable for measuring viscosity-temperature and viscosity-pressure curves of various liquids.

Viscosity and density are key thermophysical properties of substances, with important and extensive applications. Currently, there are various devices on the market for measuring viscosity and density, but relatively few instruments can simultaneously test fluid viscosity and density over a wide temperature range and under high-pressure conditions. In response to this situation, our company has launched the VM4000 series of high-temperature viscosity-density meters, aiming to meet the needs of precise measurement under special working conditions.
