Tin Side Detector Lamp is used because some chemicals, like Hydroflouric acid (found in CC550) will "smoke" or "cook" float glass.

The glass has a tin and an air side. These chemicals work safely on the air side of the glass, but will ruin the tin side. These tin detectors will identify if the side you are working on is the tin or air side of the glass.

It is recommended to test the product on a small area of the glass to make sure you will not "cook" it before applying this product to the entire window.

The Tin Side Detector is very helpful in identifying the tin side. The TS1300 lamp causes the tin to fluorescence at a frequency that is visible to the human eye.

When the TS1300 lamp is placed on the tin side surface, the tin will fluorescence and produce a milky white image that is visible to the human eye.

If you place the lamp on the non-tin side of the glass, the lack of tin results in no fluorescence and therefore only the duller image of the lamp is seen.
