The AE3600 Single Pane Low-E Detector checks both surfaces of single pane glass with one test from a single side. The AE3600 is optimized for testing sheets of glass in the factory. With one push of a button, users can determine if the meter is contacting the Low-E surface or if the coating is on surface two. There is no need to conduct a test on both surfaces of glass - a real time saver in production
