DRX-II-JG Series Laser Flash Analyzer
The DRX-II-JG series is a laser flash analyzer that determines thermal diffusivity from the rear-face temperature response to an energy pulse and can determine specific heat capacity by comparison with a reference of known specific heat capacity. Interchangeable furnace and specimen-fixture configurations support solid, liquid, melt, slag, powder, and film specimens; thermal conductivity is calculated from thermal diffusivity, density, and specific heat capacity.

Product Description
A programmed furnace conditions the specimen before the energy pulse, and a high-speed infrared detector records the rear-face temperature rise for the temperature-time analysis. Comparative specific-heat measurement uses a reference material with known specific heat capacity; the analysis software also supports thermal-resistance and multilayer thermal-contact-resistance calculations.
SiC, Al₂O₃, and metal specimen holders are offered for the appropriate test configuration. A graphite holder requires a compatible protective/inert-atmosphere configuration; inert, oxidizing, and reducing test atmospheres may be selected where compatible with the furnace and holder.
The system provides mathematical-model fitting, pulse-width correction, pulse-energy integration, thermal-loss correction, a database, computer control, and automatic report printing. The analysis software has a Chinese-language interface and uses a legacy Windows 10 64-bit environment; verify current support.
