Netzsch 402C Dilatometer
Netzsch 402C Dilatometer is used to measure the expansion or shrinkage of a material when subjected to a controlled temperature and time program.
Dilatometry (DIL) is a thermoanalytical technique for the measurement of expansion or shrinkage of a material when subjected to a controlled temperature/time program. The method is standardised and operates on bases such as DIN EN 821, DIN 51045, ASTM E 831 and ASTM E 228. Besides solid samples, powders, pastes and even liquids can be tested in special containers.
Netzsch STA 449F3 Jupiter Simultaneous Thermal Analyser
The specific heat and mass retention of the materials can be measured using simultaneous DSC/TGA thermal analyser (NETZSCH STA 449F3), which measures heat flow variation using differential scanning calorimetry (DSC) technique and the mass loss or retention using thermo gravimetric analysis (TGA) technique.
The thermo-gravimetric analysis (TGA) is a technique of thermal analysis in which changes in physical and chemical properties of materials are measured as a function of increasing temperature. TGA is commonly used to determine selected characteristics of materials that exhibit either mass loss or gain due to decomposition, oxidation, or loss of volatiles. Applications of TGA are materials characterization through analysis of characteristic decomposition patterns, studies of degradation mechanisms and reaction kinetics, determination of organic content in a sample, and determination of inorganic content in a sample.
Differential scanning calorimetry (DSC) is also a thermoanalytical method in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. Both the sample and reference are maintained at nearly the same temperature throughout the experiment. The DSC allows precise measurements of heat capacity and can be also used for calculation of enthalpies of chemical reactions.
The accuracy of this instrument for DSC and TGA measurements are +2% and +5μg, respectively. Tests can be conducted according to the standard procedures stipulated in ASTM E1269 (2011) using Platinum (Pt) crucibles lined with Alumina (Al2O3) liners and pin holed lids. The instrument was calibrated to minimize the effects of the factors such as type of cooling system, type and flow rate of purge gas, heating and cooling rates, sample mass, crucible type and instrument configuration.
Netzsch LFA 467 Hyperflash
The Light Flash (LFA) technique is a fast, non-destructive, non-contact, and absolute method for determining these thermophysical properties, including specific heat. This data can then be used for: Complete set of thermophysical properties such as thermal diffusivity (a), specific heat capacity (cp) and thermal conductivity (λ) as input data for numerical simulations.
The front surface of a plane-parallel sample is heated by a short energy light pulse. From the resulting temperature excursion of the rear face measured with an infrared (IR) detector, thermal diffusivity and, if a reference specimen is used, specific heat are both determined. Combining these thermophysical properties with the density value results in the thermal conductivity as follows:
λ(T) = a(T) · cρ(T) · ρ(T)
where
λ = thermal conductivity [W/(m·K)]
a = thermal diffusivity [mm²/s]
cp = specific heat [J/(g·K)]
ρ = bulk density [g/cm3].
Heat Flow Meter – HFM 436 Lambda
Heat Flow Meters (HFM) are exact, fast and easy-to-use instruments for measuring the thermal conductivity (λ), heat flow, R and U values of low-conductivity materials such as insulations. The HFM is a calibrated instrument which performs tests according to ASTM C518, ISO 8301, JIS A1412, DIN EN 12664 and DIN EN 12667.

Heat Flow Meters measure thermal conductivity, heat flow and low-conductivity of materials like insulation. A specimen is placed between a hot and a cold plate, and the heat flow created by the well-defined temperature difference is measured with a heat flux sensor. The HFM 436 Lambda series owe its precision and speed of measurement to the patented temperature control and heat flux measurement technology. Test results are available within minutes, with outstanding accuracy and repeatability.
