Thermal Conductivity & Diffusivity

Laser Flash Thermal Diffusivity Analyzer

The DRX-II-JG1200 uses the laser flash method to measure thermal diffusivity and specific heat, with infrared detection of the specimen rear-face temperature rise for thermal-conductivity analysis. It supports metals, alloys, ceramics, graphite, carbon fiber, polymers, liquids, films, electrical insulators, particulate materials, powders, and coal, with references to GJB 1201.1-91 and ASTM E1461.

Thermal Conductivity & Diffusivity

Product Description

The DRX-II-JG applies a pulse to a specimen and measures the temperature rise on the opposite surface with a high-speed infrared detector. Thermal diffusivity is calculated from temperature versus time, and specific heat can be measured for calculating thermal conductivity.

Applications include metals and alloys, ceramics, graphite and carbon fiber, filled plastics, polymers, liquids, films, electrical insulating solids, particulate materials, powders, and coal. Referenced standards are GJB 1201.1-91 and ASTM E1461.

The modular system supports solid blocks, low- and high-viscosity liquids, semisolids, elastic solids, and films under vacuum or protective atmospheres. This page lists one specimen per test, with up to three specimens loaded in the automatic loader; the listed furnace configurations are room temperature, 500 °C, and 1,200 °C. Thermal conductivity calculation uses measured thermal diffusivity together with density and specific heat capacity.
