GHP 456 Titan Application Example
Measurement accuracy verification: SRM 1450 c fiberglass board
The NIST standard sample 1450c (made of glass fiber board) was measured within the temperature range (0... 60 ° C) provided in the standard certificate in the figure. The deviation between the measured value and the NIST literature value is less than 1%, which is within the uncertainty range of the standard sample. This proves the superior performance of GHP 456 very well.

Styrodur: Repetitive testing
The following image uses GHP 456 Titan ®， At -100 ℃ A 5cm thick Styrodur C (polystyrene foam material) sample was measured at 25 ℃.
For each repeated measurement, the sample is taken out, flipped over, and then placed back into the furnace. The maximum deviation between the repeated measurement results is only 0.4%, indicating that the system has excellent repeatability.

PUR foam material
The insulation of modern roof tiles, refrigerated tanks, and transportation industries often require corresponding insulation materials with low thermal conductivity and high mechanical stability. Polyurethane (PUR) foam materials have both these characteristics.
The test results of GHP on the material between -160... RT are displayed here, and compared with the test results of HFM at room temperature. The two results are in good agreement. The slope change on the curve between -50... -125 ℃ is caused by the condensation effect of gas inside the material pores.

PMMA
PMMA is a transparent thermoplastic material that first entered the market in the 1930s under the trademark Plexiglas. PMMA is often used as a lightweight or shock resistant alternative to glass, for example, as a window material in the construction industry, as a cover plate or lens material in the automotive lighting or pharmaceutical engineering industries. The literature reports that the thermal conductivity of this material at room temperature is 0.19 W/m * K.
This example is from -150 Measurements were taken on PMMA plates with a thickness of 20mm within a temperature range of 25 ℃. The results indicate that even for samples with medium thermal conductivity such as PMMA, GHP can provide reliable measurement results. The deviation bar in the figure shows a measurement accuracy of approximately ± 2%.

Mineral fiber insulation material
Mineral fiber insulation materials are commonly used as insulation materials for kitchen stoves. The material was tested in the temperature range of room temperature to 500 ° C in the figure. For the vast majority of insulation materials, including this material, the thermal conductivity generally increases in a nearly linear manner around room temperature. At higher temperatures, the thermal conductivity increases faster. This can be explained as the contribution of enhanced radiation effects to the effective thermal conductivity.
Extruded polystyrene foam (XPS)

Extruded polystyrene foam (XPS)
Extruded polystyrene foam (XPS) has moderate flexibility, low density and low thermal conductivity due to its air content. XPS is renowned for its durability and reliability in natural environments. The following image shows GHP 456 Titan ® Tested 50mm Styrodur ® C Thermal conductivity of foam plate in the temperature range of -150 ℃ to 20 ℃. The values obtained at room temperature have good agreement with the theoretical values.
