TPS-Effusivity Meter
Thermal Effusivity (W√s/m2K) is described as a materials ability to exchange heat with its surroundings. Surface haptics is a branch of psychology, describing the sense of touch, localized to the skin surface. The feeling of warmth and coolness (thermal effusivity) makes up the feeling of comfort, or the desired effect, which goes into the touched material surface. This is an important field of measurement for textiles, fabrics and solids.

Thermogravimetric Analyzer
TGA-1000/1500
The Thermogravimetric Analyzer TGA-1000/1500 is a thermal analysis instrument that measures weight changes as a function of temperature or time. The system allows for multiple heating, cooling, and isothermal segments to be linked together to achieve a complex profile. Automatic gas switching is also supported during the temperature program. The vertical hangdown design offers stable and smooth weight readings to be recorded during the experiment. The TGA’s small mass furnace responds quickly to changes in the temperature profile and cools down quickly for fast turn around between experiments. Typical analyses for a TGA-1000/1500 include percent weight loss, onset temperature calculations and residual weight.

Liquid Thermal Conductivity Instruments
THW-L1
The Transient Hot Wire (THW-L1) Liquid Thermal Conductivity Meter is an advanced measurement system for direct determination of the thermal conductivity, thermal diffusivity, and specific heat instrument for measurement of liquids and pastes in accordance with ASTM D7896-19. The THW-L1 was designed with speed and operational simplicity in mind. With a single measurement of 1 second in duration, small volumes of liquids and pastes can be accurately and precisely measured for thermal conductivity, thermal diffusivity, and specific heat. The THW-L1 utilizes a non-stationary measurement approach and rapid test times to limit convective effects for samples with a wide range of viscosities. The THW sensor consists of a thin heating wire 40 mm in length and is completely inserted into the sample to be tested.

Differential Scanning Calorimeter
DSC-L600
The Differential Scanning Calorimeter (DSC-L600) is a powerful thermal analysis instrument that measures the heat flow of a sample as a function of time or temperature. The DSC-L600 has been designed to be a cost-effective instrument that is well suited for research or QC applications. The instrument communicates with the PC via a RS232/USB connection. The specially designed heat flux plate has demonstrated more than twice the sensitivity than other heat flow type DSC’s on the market. The reproducibility is excellent, and the noise level is virtually unnoticeable due to a precision high gain, low noise differential amplifier

THW-L2
Designed with speed and operational simplicity in mind, the Transient Hot Wire (THW-L2) Liquid Thermal Conductivity Meter is an advanced measurement system for direct determination of the thermal conductivity of liquids and pastes in accordance with ASTM D7896-19. In less than 2 seconds, a single measurement of small volumes of liquids and pastes can be accurately and precisely measured for thermal conductivity. Using a non-stationary measurement approach, the THW-L2 uses rapid test times to limit convective effects for samples with a wide range of viscosities. The THW sensor consists of a 60 mm heating wire that is fully inserted into an isothermal sample. A constant current source (q) is used to heat the sensor wire and the temperature rise is recorded by monitoring the change in electrical resistance of the wire. The slope (m) is determined from the plot of temperature rise vs. logarithm of time and is used in the calculation of thermal conductivity (λ). Liquid samples of high thermal conductivity will have a lower slope, while liquid samples with low thermal conductivity will have a higher slope.
