ThermCon Scientific’s HFM 300 series thermal conductivity meter is a heat flow meter-based guarded hot plate type thermal conductivity test device, capable of measuring samples with dimensions of 300 x 300 mm and thicknesses ranging from a few millimeters up to 100 mm. This device is primarily used to test the thermal conductivity and thermal resistance of construction materials, insulation materials, glass, fiber, foam, and similar substances. Testable materials include fiberboard, loose-fill glass fiber, rock wool, ceramic fiber, foam plastic (XPS/EPS/PUR, etc.), sandwich composite panels, vacuum panels, cement (concrete) products, glass stone wool, fillers, drywall, and similar materials.

The HFM 300 measures the thermal conductivity coefficient in compliance with national and international standards, such as GB/T 10295, ISO 8301, JIS B 1412, DIN EN 12667, EN 12939, EN 12664, and ASTM C518 "Standard Specification for Rigid Cellular Polystyrene Thermal Insulation." The device ensures full compliance with national thermal conductivity measurement standards through its stable and precise temperature control technology, computer interface, real-time monitoring and control software, as well as data processing and recording functions.

Application Areas Thanks to These Advantages Thanks to these advantages, the HFM 300 series is widely used in material properties testing centers, scientific research institutes, factory quality control units, and in the teaching and research activities of higher education institutions.
