IPI's New Tool: The Dew Point Calculator

The Dew Point Calculator is now available online! Visit www.dpcalc.org to explore its features.

The Dew Point Calculator allows you to:

• Explore the relationship of Temperature, Relative Humidity (RH), and Dew Point.
• Explore the preservation consequences of environmental conditions with respect to Natural Aging, Mechanical Decay, Mold Growth, and Metal Corrosion.
• Help plan, evaluate, and manage storage environments with respect to preservation benefits, preservation risks, or the realities and capabilities of your system.

The Preservation Evaluation section includes IPI's environmental ratings and preservation metrics, which analyze the preservation quality of the hypothetical storage environment represented on the calculator. This analysis allows you to quickly interpret how this combination of Temperature, RH, and Dew Point would affect your collections.

The Dew Point Calculator is a web-based application, so no download is necessary. In addition, the Dew Point Calculator can be used with any web browser (Firefox, Internet Explorer, etc.) on a Macintosh or a PC.

To learn more about how the Dew Point Calculator can be applied to environmental monitoring, refer to the articles within this newsletter: Understanding Dew Point, Why is Dew Point Important for Managing my Environmental Conditions?, and Winter Dryness and Its Effects on Collections.
