IX. Comfortmeter Instructions
(Thermometer/Hygrometer)
This Comfortmeter is a combination of both temperature and humidity
indicators. Calibration and positioning of hands are designed to indicate
perfect comfort conditions when both hands cross in a limited area of the
dial, the C O M F O R T Zone. Both temperature and humidity indicators
are accurately calibrated at the factory and normally require no adjustment.
Hygrometer
The Hygrometer will indicate the relative humidity of the atmosphere.
While indoor and outdoor barometric pressure is the same, relative humidity
indoors is not always the same as the relative humidity outdoors. Therefore,
remember that this instrument when used indoors indicates the humidity of
room atmosphere which has no relation to the outdoor humidity readings
announced on weather reports.
