Lowe's Graphic Hygrometer

Nathaniel M. Lowe, the manufacturer of Edson's Hygrodeik, designed a similar but somewhat simpler instrument for showing the dew point and relative humidity. In this example, the chart is on a white enamel plate marked "LOWE'S Graphic hygrometer" and a monogram. It came to the Smithsonian from Trenton State University.
