The CRL Glass-Chek Elite is an effective instrument which identifies laminated glass in a window, and also measures the thickness of the laminate inner-layer. It contains a graphical display that shows an illustration of the profile of the window, helping the user to better understand the construction of the window. It also shows the window drawn approximately to scale, and assigns numbers to each piece of glass in the window, and also assigns numbers to each surface of glass, aiding in identifying the Low-e coated surface.
