It simultaneously measures liquid viscosity and density, offering high precision, excellent repeatability, and automated operation. Its sealed chamber makes it particularly suitable for measuring volatile liquids.

Viscosity and density are key thermophysical property indicators of substances, with important and extensive applications. Currently, there are various devices for measuring viscosity and density on the market, but instruments capable of simultaneously testing fluid viscosity and density under a wide temperature range and high-pressure conditions are relatively few. In response to this situation, our company has launched the VM4000 Series Low-Temperature Viscosity-Density Meter, aiming to meet measurement needs under special working conditions.

Key Features

l  Multi-parameter measurement: Capable of simultaneous measurement of viscosity and density, enabling the acquisition of viscosity-temperature curves, viscosity-pressure curves, and calculation of viscosity-temperature coefficients and viscosity-pressure coefficients.

l Wide temperature measurement range: Allowing viscosity measurement within -30~100℃, with support for customization of lower or higher temperatures.

l Wide pressure measurement range: Equipped with a pressure control module, enabling viscosity measurement within 0.1~15 MPa, with support for customization of higher pressures.

l High precision and stability: Adopting the vibrating wire method, it offers high measurement accuracy and good repeatability, free from the influence of surface tension and interfacial tension.

l Fully automated operation: Supporting functions such as automatic temperature control, automatic pressure application, and automatic sample injection, it is easy to operate and reduces labor costs.

l Sealed test chamber: Suitable for measuring volatile liquids, ensuring the safety and accuracy of the measurement process.

l Professional software support: Equipped with a concise and intuitive testing software that supports automatic data collection and analysis, facilitating users to quickly obtain reliable data.
