一种高精度建筑外门窗三性检测设备

在国内建筑外门窗物理三性检测设备的基础上，结合新方法标准对外门窗气密性能检测的要求，改善检测设备静压箱与空气收集箱的结合方式，大大减小设备箱体的附加渗透量，制备出符合新标准高精度的建筑外门窗物理三性检测设备。

A high-precision testing equipment for three properties of building exterior doors and windows

On the basis of the physical three-character testing equipment for building exterior doors and windows, combined with the requirements of air permeability performance for exterior doors and windows in new standard, the combination of the static pressure box and the collective box of the testing equipment is improved, and the volume of extraneous air leakage of the equipment is greatly reduced. The high-precision physical property testing equipment for external doors and windows in line with new standard is prepared.
