THERMAL CONDUCTIVITY AND DIFFUSIVITY METER FOR NON-METALLIC MATERIALS ITS-λа-20

SKU0066
DESCRIPTION

The automated device is designed for determining the thermal conductivity λ and thermal diffusivity λ of homogeneous dense solid non-metallic materials under normal conditions: open environment and room temperature of approximately 20 °C. The device consists of a thermal measurement cell and a specialized thermophysical controller TFK-2.2.

CHARACTERISTICS

  • Measurement Range:
Thermal conductivity λ: (0.15…1.0) W / (m × K).
Thermal diffusivity a: (1.0...5.0) × 10^-7 m^2/s.
  • Temperature Range for Measurement: (25 ± 5) °C.
  • Test Objects: Homogeneous dense solid non-metallic materials.
  • Sample Dimensions and Shape: Flat plates sized (30×30) + 0.1 mm, thickness (4.0…15) + 0.1 mm, cut or stamped from the test material. Flat surfaces must be ground on a lapping plate, with wedge tolerance not exceeding 0.05 mm.
  • Experiment Duration: 3 to 30 minutes (depending on sample properties).
  • Measurement Accuracy:
Thermal conductivity: ± (5–7)%.
Thermal diffusivity: ± (7–10)%.
  • Power Supply: 220 V, power consumption up to 10 W.
  • Operator Interaction: Real-time monitoring of experiment progress via a graphical display.
