Weems and Plath brass Comfortmeter is designed to indicate when conditions are the most comfortable.
The device monitors both temperature and humidity, and when both dials cross a designated area of the scale, the comfort zone has been reached.
Aside from the comfort zone, the comfortmeter also displays a wide variety of other, less comfortable conditions. The porthole style opening bezel display shows relative humidity percentages on the right hand side, while temperature readings appear on the left.
