COMFORT HUMIDITY INDICATOR

摘要

A weather instrument including a hygrometer and an outdoor thermometer, an indoor thermometer, and means operatively associated therewith for providing an indication of the relative humidity required to maintain a predetermined temperature-humidity relationship. In one embodiment, a cam-filament arrangement responds to a manual positioning, in accordance with information derived from integral measuring devices, to automatically provide an indication of the relative humidity required to maintain a predetermined temperature humidity relationship. The deviation between ambient and optimum humidity is ascertained by comparison of the coaxially mounted instruments indicating these two conditions.
