Simultaneous measurement of liquid viscosity and density across the -30~200℃ range, ideal especially for volatile liquids. It delivers high accuracy, excellent repeatability, ease of use, and automated operation.

Viscosity and density are key thermophysical properties of substances, playing important and extensive roles. Currently, there are various devices on the market for measuring viscosity and density, but instruments capable of simultaneously testing fluid viscosity and density under high-temperature and high-pressure conditions are relatively scarce. In response to this situation, our company has launched the VM4000 series liquid viscosity and density meters, aiming to meet the 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, as well as the calculation of viscosity-temperature coefficients and viscosity-pressure coefficients.

l Wide temperature measurement range: Allowing viscosity measurement from -30 to 200 ℃, with support for customization for lower or higher temperatures.

l Extensive pressure measurement range: Equipped with a pressure control module, it can achieve viscosity measurement from 0.1 to 15 MPa, with support for customization for 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 Automated operation: Supporting automatic temperature control, automatic pressure application, and automatic sample injection, it is easy to operate and helps reduce labor costs.

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

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