Applications of Thermal Conductivity Meters for Insulation Materials

A thermal conductivity meter for insulation materials is used to determine the thermal conductivity of solid materials commonly employed in building and industrial insulation. Typical test specimens include fiberboards, loosely packed glass fibers, ceramic fibers, polymer foams such as XPS, EPS, and PUR, laminated composite panels, vacuum insulation panels, rubber products, cement-based products, powders, fillers, and gypsum boards. These instruments comply with GB/T 10294-2008 (guarded hot plate method), ASTM C518, and ISO 8302, ensuring reliable and comparable results across international standards. Based on the original DRX-I-PC double-plate technology, the system has been significantly upgraded to enhance accuracy and stability. Key improvements include triple thermal protection to minimize environmental heat interference, automatic parallel alignment between the sample and the hot/cold plates to reduce non-parallelism errors, and an electronically cooled cold plate with options for water or other coolant media. The platform features stable temperature control, a computer interface, real-time software monitoring and control, data processing, and data storage capabilities to support rigorous measurement workflows. It fully meets national requirements for thermal conductivity measurements and is well suited for materials testing institutes, research organizations, factory quality control departments, and university teaching and research. The thermal conductivity meter is available in horizontal and vertical configurations. Appearance and specific form factors may vary by production batch and should be confirmed with the final delivered unit.
