The Glass-check insulated glass thickness gauge is the perfect tool for measuring the total glass element thickness of panes or insulating glazings when installed. In addition, an optical glass thickness gauge is mounted on the GlassCheck: simply place the stop surface with the baseline on the disc and, where the weaker reflection matches the scale, read the glass thickness of each disc. With the Glass-check, you will always know exactly how thick your glass is, ensuring that your installation is always up to code.
