Transient Hot-Wire Liquid Thermal Conductivity Analyzer is a precision instrument designed for accurate measurement of thermal conductivity, thermal diffusivity, and specific heat of liquids, pastes, and powders. Based on the transient hot-wire (THW) method and compliant with ASTM D7896-19. the system enables fast, reliable, and repeatable thermal property characterization using a small sample volume and ultra-short measurement time. It is especially suitable for liquid and phase change material analysis under a wide temperature and pressure range.
Application
The Transient Hot-Wire Liquid Thermal Conductivity Analyzer is widely used in research, development, and quality control environments where accurate thermal property data of fluids and semi-fluids is required. Typical application scenarios include:
Engine coolants, lubricants, and heat transfer fluids
Phase change materials (PCM) for thermal energy storage
Chemical liquids and pastes used in process engineering
High-viscosity fluids and suspensions
Research on thermal transport mechanisms
Typical tested products include engine coolants, PCM slurries, silicone oils, polymer solutions, and specialty chemical fluids.
Standards
The analyzer is designed and tested in accordance with internationally recognized standards:
(1) ASTM D7896-19 — Standard Test Method for Thermal Conductivity, Thermal Diffusivity, and Volumetric Heat Capacity of Liquids Using the Transient Hot-Wire Method
