The first portable thermal conductivity instruments
with low absolute uncertainty: 2% for solids, 1% for liquids
Measurement of the thermal conductivity of solids and liquids
This is the first low-uncertainty Transient Hot-Wire instrument
An easy to use Guarded Heat-Flow instrument
Machine Learning state-of-the-art
A cutting edge software suite, is developed for the mesh describing the structure of the sensor designed for the measurement of the thermal conductivity of solids. The suite utilizes the Finite Elements Method to model the heat flow and the estimation of thermal conductivity is modelled as a minimization problem, and solved using a Bayesian Optimization technique.
The developed software coupled with the newly designed compact portable printed electronic board employing an FPGA architecture CPU to the control output voltage and data processing, allow the absolute calculation of the thermal conductivity of solids within 2% uncertainty.
