Dri-Eaz introduces the Digital Psychrometric Calculator. Not much larger than a business card, the calculator is “loaded with practical functions to help make it easier for restorers to consistently incorporate the science of psychrometry into their everyday work,” the company said.

The DPC performs calculations of grains per pound (GPP), thirst and dew point; figures GPP to gram per kilogram; converts temperatures between Celsius and Fahrenheit, and more.
