WL 420 Heat conduction in metals
WL 420 Heat conduction in metals
The GUNT WL 420 Heat Conduction in Metals unit allows for the investigation of heat transfer properties in various metallic materials. The system enables users to measure thermal conductivity by analyzing the temperature distribution along metal samples subjected to controlled heating. Equipped with precise temperature sensors, the unit provides accurate data for evaluating heat conduction behavior. Ideal for laboratories and educational institutions, WL 420 offers hands-on training in fundamental thermodynamics and materials science.
More about the productGUNT WL 420
Unit is part of the GUNT-Thermoline series, designed for studying the fundamentals of heat transfer.
It enables the investigation of the thermal conductivity of different metals using a continuously adjustable heater and a Peltier element for cooling.
The system includes 11 metal specimens of different lengths and materials.
The integrated microprocessor-based instrumentation eliminates the need for additional devices with complex wiring.
Data acquisition and system operation are managed via the GUNT software, which allows network connectivity (LAN/WLAN) for multiple workstations.
Additional multimedia learning materials are available online.
