Heat and Mass Transfer Lab Equipment

Guarded Hot Plate with data acquisition


DESCRIPTION: The “LabTek “Offers basic experiments 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 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.

The experimental unit is equipped with temperature sensors at the inlet and outlet of the air duct. The air velocity is measured to determine the airflow rate. Heating power and flow rate are adjusted and displayed via the software.

The microprocessor-based instrumentation is well protected in the housing. The software consists of software for system operation and for data acquisition and educational software. is connected to the PC via USB.
