ASTM E1461 LDR-II Transient Laser Thermal Conductivity Tester Thermal Analyzer Precision Instrument

ASTM E 1461 LDR-II Transient Laser Thermal Conductivity Tester
Thermal Diffusivity Testing Machine
Product Overview
The LDR-II Transient Laser Thermal Conductivity Tester is designed for precise measurement of thermal diffusivity and thermal conductivity in high thermal conductivity solid materials, including metals, graphite, and similar materials.
Key Features
  • Compliant with GB/T 22588-2008 and ASTM E 1461-2001 standards
  • Patented technology (Certificate number: 13751552)
  • Fast measurement speed with accurate results
  • Suitable for metals, graphite, graphene, silicon carbide, and other high thermal conductivity materials
  • Computer-controlled automatic testing with report generation
Measurement Principle
The instrument uses a high-intensity short-duration energy pulse to irradiate the sample. The temperature change on the back surface is recorded, and the thermal diffusivity (α) and thermal conductivity (λ) are calculated based on the half-heating time using specialized mathematical models.
