Description

Technical Field

[0001] This utility model relates to the field of wind speed measurement technology, specifically a wind speed measuring device. Background Technology

[0002] Pass-through windows, isolators, and open-access restricted-access isolation systems are devices that can provide a clean environment. Their validation process is particularly rigorous, especially the wind speed test, which can directly affect the air exchange rate of the equipment and thus determine the level of clean environment provided. This leads to the following problems frequently occurring during the validation process:

[0003] Due to equipment limitations, wind speed could not be measured under normal operating conditions (with the door closed), which required the door to be opened for testing during the verification process, thus affecting the wind speed near the door.

[0004] Currently, when verifying wind speed using equipment, the method of manually holding the anemometer is used. However, it is difficult to accurately determine the holding height and the center distance between the points, which leads to certain errors in the measurement results. Utility Model Content
