Upcoming Webinars
Thermal Conductivity and Resistance of Rigid Compressible Insulation
Date: January 27th
For the measurement of rigid and compressible insulation material, thermal conductivity results calculated from measured thermal resistance is the preferred method.
Homogeneous and Heterogeneous for Transient & Steady State Methods
Date: February 9th
When measuring homogeneous or heterogeneous materials, it is important to consider steady-state vs. transient testing methods and how this will influence the measurement of thermal conductivity.
Recorded Webinars
Comparing the Thermal Conductivity Measurements of Liquids using Various Transient Methods
In this webinar, we compare which transient method is ideal for liquid. The transient methods explored will be Hot-Wire, Line Source, and Plane Source.
Powerful New ThermoReflectance Instrument for Measurement of Nano/Micron Scale of Coatings and Films
Steady-state thermoreflectance (SSTR) is an optical measurement technique used to measure the thermal conductivity or boundary conductance of thin films and coatings.
Thermal Effusivity to Simulate and Measure Cool Feel Flooring
In this webinar, we compare various types of laminate flooring to authentic hardwood, qualitatively comparing the results attained using our Thermal Effusivity Meter (TPS-EFF).
Thermal Conductivity and Resistivity of Solid Materials using the TLS-100
The transient line source technique can be used for the thermal conductivity and resistivity of solid materials such as concrete, natural stone, and low thermal conductivity ceramics. Dr. Cederkrantz discusses his measurements on the materials using the TLS-100. For in-situ and lab testing using the Transient Line Source: TLS-100.
Measuring the Thermal Conductivity of Fresh and Used Engine Oil
Engine oil is an important heat transfer fluid in combustion engines. Overtime, engine oil degrades from heat, pressure, and the collection of debris. Thermtest’s principal scientist, Dr. Sofia Mylona, will investigate the thermal conductivity of new vs. used engine oil and explain her findings in this webinar.
Touch-Times and Steady State Testing of Foams
As the bedding industry encompasses measurements of comfort for feeling of coolness or warmth, also known as Thermal Effusivity, for both initial touch and steady-state sleeping. This webinar will cover how these comfort factors can be measured and used in design in the bedding industry.
Thermal Conductivity of Nanofluids with the Transient Hot Wire (THW-L2)
In this webinar, our in-house expert will briefly compare thermal conductivity methods for testing liquids and the advantages of testing liquids with the THW-L2.
Thermal Conductivity and Thermal Resistance Testing of Polymers and Composites with Guarded Heat Flow Meter
For the measurement of non-homogenous and layered materials, thermal conductivity results calculated from measured thermal resistance is the preferred method. A comparison of thermal conductivity ASTM / ISO standards and investigative testing will be presented to explain why this is the case.
Measuring the Effects of Moisture Wicking Fabrics and Thermal Effusivity
In this webinar featuring Moisture Wicking Fabrics, we discuss our findings on the effects of moisture wicking fabrics and cool feel performance wear using the Thermal Effusivity Meter (TPS-EFF). Our focus is determining if the TPS-EFF can assist in selecting cool feel materials to be used in athletic wear with varying moisture levels.
Thermal Conductivity of Soil and Concrete using the Transient Line Source Technique
Discussing the measurement of the thermal conductivity and resistivity of soil and concrete using the transient line source technique. The transient line source (TLS) is an ideal and standardized method for testing materials in-situ and in the lab. Thermtest’s TLS-100 is an easy-to-use and affordable instrument used for testing soil, rocks, concrete, and polymers.
Thermal Conductivity of Heat Transfer Fluids using the Transient Hot-Wire Technique
Discussing the benefit of using the Transient Hot-Wire (THW) method for heat transfer fluids such as ethylene glycol and water. Transient Hot-Wire (THW) is the primary method for the measurement of thermal conductivity of fluids, nanofluids and pastes because of the wide range of applications, its high accuracy and repeatability. – Presented by: Dr. Sofia Mylona, Transient Hot-Wire technique Expert
