The Low-E CARD® (Disposable) and Low-E CARD+ (Replaceable Battery) will confirm if there is a Low-E coating on the piece of glass you place it against. There are no metal contacts to scratch the glass surface. Therefore, it is safe to use on the glass, even if it is dirty or has a label or other insulating layer. For orders of 100 pieces or more, you can brand the Card with your company logo and sales message. Now you can offer your branded card for use in the factory or give it to customers to raise brand awareness.
