Laser Flash Analyzer

The DRX-II-JG measures thermal diffusivity with the laser flash method and infrared detection of the specimen's rear-face temperature rise. It can also measure specific heat and calculate thermal conductivity from thermal diffusivity, density, and specific heat capacity for metals and alloys, diamond, ceramics, graphite and carbon fiber, filled plastics, polymers, liquids, films, electrical insulating solids, particulate materials, powders, and coal.

The series uses a modular design and can measure thermal diffusivity, thermal conductivity, and specific heat for 3–6 specimens simultaneously. Different specimen holders support solids, liquids, melts, and slag; hardware and electronic components are separated, and an enclosure can be installed for nuclear applications.

The measurement procedure heats the specimen to a programmed temperature, and a high-speed infrared detector measures the temperature rise at the rear face of the specimen. Thermal diffusivity is calculated from temperature-versus-time data. Vacuum and protective-atmosphere measurement, multilayer thermal-contact-resistance analysis, computer control, and comparative specific-heat measurement with a reference specimen are available.
