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
Test Procedures
Sample Preparation
Pour approximately 20 mL of liquid into the selected sample element. The short test duration effectively suppresses convection, allowing accurate measurement across a wide viscosity range. Back pressure up to 35 bar can be applied for measurements above the boiling point.
Approximate time: 1 minute
Sensor Insertion
Insert the THW sensor into the sample element and place it into the integrated temperature platform for controlled testing.
Approximate time: 1 minute
Measurement Execution
The software automatically controls isothermal steps from -150 °C to 300 °C, depending on configuration.
Approximate time: < 1 minute
Result Output
The Windows-based software verifies measurement validity, suggests adjustments if required, and generates reports. Results can be saved, exported to Excel, or sent via .
Approximate time: 1 minute
Maintenance Information
Keep the THW sensor clean and free of residue after each test
Inspect sensor integrity regularly to ensure stable resistance behavior
Verify temperature control performance periodically
Store sample elements in a clean, dry environment
Follow standard laboratory practices for handling liquids and phase change materials
