Advanced Thermal Property Measurement Platform: MP-1
The MP-1 is designed to test the absolute thermal conductivity, thermal diffusivity, specific heat, and thermal effusivity of solids, liquids, pastes and powders with the powerful combination of multiple methods.
- Transient Plane Source (TPS): ISO 22007-2, ISO 22007-7, GB/T 32064 (solids)
- Transient Hot Wire (THW): ASTM D7896 (liquids)
- Modified Transient Plane Source (MTPS): ISO 22007-7:2023
- Transient Line Source (TLS): ASTM D5334-22a, ASTM D5930
- Transient Hot Strip (THS)
The powerful combination of Transient Plane Source (TPS), Transient Hot Wire (THW), Transient Line Source (TLS) and Transient Hot Strip (THS) gives the MP-1 a unique and versatile selection of testing methods for your sample type. The TPS and THW methods are widely used for accurate measurement of absolute thermal conductivity, thermal diffusivity, specific heat and thermal effusivity. This versatility is greatly expanded with the addition of our proprietary Temperature Platform (TP) which is appreciated by academic and commercial users alike.
MP-1 Methods:
Transient Plane Source (TPS) Sensor
The TPS sensor designed for solids, pastes and powders is comprised of a double-spiral of nickel encapsulated between layers of insulation. Standard operation of this sensor (Two-Sided) is placed between two pieces of the same sample, with expanded use to Single-Sided sensor, which only requires one piece of sample (Single-Sided). Our proprietary TPS calculation model measures the contact resistance between sensor and sample, as well as the thermal conductivity, thermal diffusivity, volumetric specific heat and thermal effusivity of the sample.
Transient Hot Wire (THW) Sensor
The THW sensor designed for liquids and phase change materials (PCMs) consists of a replaceable thin heating wire (40 mm in length) secured to specially designed sensor and sample cell which allows back pressurizing liquids to measure thermal conductivity, thermal diffusivity and volumetric specific heat past boiling temperatures. Measurements are done at short test times (1 second) to limit convective effects on samples with a wide range of viscosities.
Transient Line Source (TLS) Sensor
The TLS sensor designed for soil, paste and polymers consists of a thin heating wire and temperature sensor sealed in a steel tube. The sensor is completely inserted into the sample to be tested. Heat is delivered to the sample using a constant current source (q) and the temperature rise is recorded over a defined period of time. The slope (a) from plot of temperature rise versus logarithm of adjusted time is used in the calculation of thermal conductivity (k).
Transient Hot Strip (THS) Sensor
The THS sensor shares the same theory and sample configuration as the TPS sensor, with the unique ability to measure complex shapes. Results include thermal conductivity, thermal diffusivity, and volumetric specific heat of the sample. Bulk, Anisotropic, and Slab modules available.
