The air duct temperature testing system is a professional testing device for hair dryers (air ducts) in working conditions. It fully complies with the requirements of the UL859 international safety standard. Install the system on the computer and connect it to the RS-23S/USB interface to test the data through the interface panel. And provide real-time demonstration and analysis of the data Can be used for 24-hour automatic testing. The characteristic of the data acquisition instrument of the wind duct temperature life testing system is that it can simultaneously collect up to 60 temperature points. Customers can analyze various temperature charts and collect data on the computer. The hottest five temperature positions of the wind duct can be displayed, and the temperature display of the entire test surface can be seen. These are not achievable by other acquisition instruments, and play an important technical reference value for the quality evaluation of the wind duct. It is also a necessary testing method in the wind duct industry, and is therefore adopted by major quality inspection institutions.
