Thermal Conductivity of Non-Metallic Materials (Guarded hot plate method, Computer Interface)
This bench top unit is for testing of thermal conductivity of non-metallic materials using guarded hot plates per ISO8302 and 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 inserted 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 heater control unit, and measuring instruments.
The unit requires outside water supply.
Instruction manual is also included.
