Description

The equipment operation involves passing air through a duct, which is heated up by a series of elements with different geometric surfaces. A fan is installed for the study of forced convection .

The equipment has a hand-controlled module, and can also be connected to a computer by a USB. In addition to reading all the values, the equipment can be controlled from the software display on the PC (PC and software are not included).

The equipment to be used from a computer requires a 64-bit Operating System for Windows 7 or a later version.
