Building Door and Window Detector
Overview
The Building Door and Window Field Detector is a new portable device developed by our company. It enables manual adjustment of air pressure, displaying the instrument's cycle detection results including air pressure, airflow, and deformation displacement. The wind source and control system are integrated into a suitcase, making it compact, lightweight, durable, and easy to use.
