| industries for its energy saving, environmental friendly, | | | | PERME W3/330 Water Vapor Transmission Rate |
| long life and other advantages. Usually, the life span of | | | | Test System for solar battery back sheet testing. |
| solar batteries is designed up to more than 25 years. | | | | Labthink PERME W3/330 Water Vapor |
| To achieve such long validity, a strict control of | | | | Transmission Rate Test System, with its patent |
| component quality should be guaranteed. Of all the | | | | chamber design, can accomplish group testing of 3 |
| components, the back sheet of solar battery is of | | | | individual or similar specimens with different results. |
