One of the well-known indicators of sealed insulating glass window performance is revealed by careful measurements of air space dew/frost point and its rate of increases. The D-100 apparatus is a special apparatus developed specially for this purpose. It is the test apparatus of ASTM Standards, E-546 ,E-576, and IGCC Standard for frost point measurement. This D-100 apparatus was selected as 1975 Winner of the 13th Annual IR-100 Award Competition conducted by Industrial Research Magazine to select the 100 most significant new technical products of each year... It is easy and quick to use; it is reliable and repeatable. Using a digital temperature readout of 0.1 F (or 0.1 C) resolution, the temperature can be easily controlled within 0.2 F (or 0.2 C). Using a bimetallic dial thermometer of 2 F (or 1 C) scale, the temperature can be controlled within 2 F (or 1 C) Reproducible dew/frost point is measurable well within 1 F (or 0.5 C) and 2 F (or 1 C), respectively.
