    • A portable gauge and method are used to determine an as installed property of a loose-fill insulation in a building cavity wherein the cavity has a given depth, an open front, a rear surface, and sidewalls defined by spaced apart framing members. The gauge includes a frame for extending between and overlapping front surfaces of the framing members to position the gauge for determining an as installed property of the insulation; a plunger assembly mounted on the frame for compressing a portion of the insulation in the cavity to a compressed density sufficiently dense to prevent plunger creep and to a compressed thickness less than the as installed thickness of the insulation; and a readout assembly calibrated to indicate an as installed property of the insulation based on the compressed thickness of the insulation.
    • 使用便携式仪表和方法来确定建筑空腔中的松散填充绝缘体的安装性质,其中空腔具有给定的深度,敞开的前部,后表面和由间隔开的框架构件限定的侧壁。 该计量器包括用于在框架构件的前表面和重叠的前表面之间延伸的框架,以定位该计量器以确定绝缘体的安装性质; 安装在框架上的柱塞组件,用于将空腔中的绝缘体的一部分压缩至足够致密的压缩密度,以防止柱塞蠕变和压缩厚度小于绝缘体的安装厚度; 以及读出组件,其校准为基于绝缘体的压缩厚度指示绝缘体的安装性能。
