Introduction
Transient Plane Source Method (TPS）is invented by a Sweden Scientist Dr. Silas Gustafsson in 1991. The draft version of an international standard for TPS is firstly issued in 2008, and it is updated in 2022.
A-500 Thermal Constants Analyzer is one of the most advanced TPS instruments manufactured by FOREDA, which can measure almost all types of materials commonly used in the industries or daily life.
Properties
-
Three parameters, thermal conductivity, thermal diffisivity, and volumetric heat capacity can be obtained with one single test
-
Test is done in seconds without balancing the electrical bridge;
-
Test Data can be saved in Excel format for further applications;
-
Software can be run in any Windows computer for off-line data analysis;
-
Very large thermal conductivity range: almost all kinds of materials can be tested;
-
Applicable for all kinds of specimens: solid, liquid, gas, powders, colloid, anisotropic; or cylindrical, triangle, films, slabs, etc.;
-
Specimens Easily prepared: only one flat surface is required;
-
Absolute measurement without calibration;
-
Possibly very large temperature range: - 270 ~ 1000℃.
