Features
Transient hot-wire method with ultra-fast 1-second measurement
High accuracy and excellent repeatability for liquid thermal properties
Non-steady-state measurement minimizes convection effects, even for high-viscosity samples
Small sample volume requirement (20 mL)
Wide viscosity, temperature, and pressure measurement capability
Fully compliant with ASTM D7896-19
Accessories
(1) Paste and PCM element — Designed for easy loading of phase change materials; spring-loaded structure accommodates thermal expansion and contraction while maintaining contact with the THW wire
(2) Observation element — Glass viewing port for monitoring sample conditions such as phase separation, boiling, or particle sedimentation
(3) Ambient density powder element — Suitable for basic powder testing at ambient pressure
(4) Variable density powder element — Spiral compression system allows density adjustment and stable wire contact
(5) Vertical element holder — Enables vertical loading for paste, PCM, and powder elements
(6) Cooling system options —
Economic circulator: down to 0 °C
Circulator: down to -15 / -35 / -50 °C
Advanced options: down to -100 / -150 °C
