DEW POINT

Dew point is a measure of the absolute amount of water vapor in the air

expressed as a temperature reading. The temperature reading represents the

temperature at which water condenses from the air. If temperature and dew

point are the same, the result will be fog and/or dew. Dew point can be dis-

played in either ˚F or ˚C, in increments of 1˚.

The Weather Monitor II also records high and low dew points, and has a spe-

cial dew point alarm to alert you when temperature comes within 2˚F (1˚C) of

dew point.

Because dew point is dependent on water vapor (humidity), if you do not have

the External Temperature/Humidity Sensor, all dew point displays will appear

with a series of dashes in place of a dew point reading.

See the booklet included with the External Temperature/Humidity Sensor for

instructions on displaying dew point.
