EDTM’s Glass-Chek Elite GC3200 measures a window’s glass and air space thickness, and identifies the surface location and type of low-emissivity coating. The ELITE can also identify laminated glass and measure the inner-layer thickness of the lamination. The graphical display illustrates the window profile, labeling each glass surface, and simplifying the window construction and low-e location. The GC3200’s ability to store recent measurements in its memory saves time in the field. If users replace any windows in the field, the GC3200 can eliminate thickness mistakes, and it helps to ensure users are replacing the window with the same type of low-e coating that is being removed.
