• The air flows past a heating element and absorbs heat.
• Four heating elements with different geometries are available to be selected.
• The heating elements are designed in such a way to release heat only at their surface.
• The compact design ensures rapid heating and a short time for experiments.
• 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 a software for system operation and for data acquisition and an educational software is connected to the PC via USB.
