Suitable for colleges and universities, research institutions, insulated glass production enterprises, and related third-party testing units.

1、 Product Description

The ZDK-III hollow glass dew point meter is an instrument manufactured according to the technical conditions specified in the dew point measurement section of the standard GB/T11944-2012 "Hollow Glass". An automatic testing device used to detect whether condensation occurs on the inner surface of insulated glass samples under standard conditions and methods. It can also test the airtightness of insulated glass. Under ideal sealing conditions, insulated glass should not produce condensation. The ZDK-III dew point meter adopts semiconductor three-stage refrigeration, with a low temperature of up to -70 ℃. It is easy to operate, only requires a 220V power supply, and does not require other auxiliary equipment. The cooling speed is fast and the cooling capacity is large. At the same time, it is equipped with a timing function that can automatically prompt, making the test more convenient and simple.
