TH 312 THERMAL CONDUCTIVITY OF NON-METALLIC MATERIALS, Guarded hot plate method
GENERAL DESCRIPTION
This bench top unit is for testing of thermal conductivity of non-metallic materials using guarded hot plates bases on ASTM C177-04.
The equipment consists of a central heater with hot plates, a guard ring with heater and hot plates, and two water cooled cold plates. Two specimens are insterted between the hot plates and cold plates. The assembly is encased in a test cabinet with insulation. The cold plates are clamped together to provided a uniform pressure.
A service module provides power supply and heater control unit, power measurement unit and temperature indicators. The unit requires outside water supply.
TYPICAL EXPERIMENTS
- Determination of thermal conductivity.
