A thermometer does not have a dew point.
A thermometer is a fixed volume system where the temperature measurement capability is based on the material. As temperature changes, the density of the material expands or contracts. This implies the material used is in a liquid state.
By simple definition, the dew point is the temperature as which a material in the gas state condenses to a liquid.
additional. Dew point is a measurement made to determine the Relative Humidity of the atmosphere. In practice, it is a tiny mirror, which can be heated or cooled automatically, thus determining the dew point.
A light beam looks at the mirror, and when there is slight misting, the light intensity and focus are degraded, and that is the dew point. A built in thermometer measures the actual temperature.
So it is a complex, but small instrument consisting of :- a mirror, a heating and cooling circuit, a thermometer, and an optical scanner.
Dew point is considered an accurate measure of humidity, and since we also know the atmosphere's temperature, the relative humidity may be determined.

What is the dew point and what happens when it falls below the dew point?
The Dew Point is the temperature at which the air is at 100% Relative Humidity. If the temperature fall below the Dew Point, then there is more moisture in the air than it can hold, and water condenses in the form of dew, mist, rain, etc.
Under what conditions will dew not form?
If the temperature of the ground, grass, and other surfaces is warmer than the dew point of the air that comes in contact with the surfaces, dew will not form. Sometimes this happens when the air is really dry and the dew point is very low.
What is the dew point in a hurricane?
there is no dew point of a hurricane
What is dew point in weather reports?
Dew point is the point when condensation forms
What happens when water vapor rises and cools the dew point?
when air contains as much water vapor as it can . it said to be structured and condensation can occur. the temperature at wich this takes place is called the dew point.
Describe what happens when air is cooled to its dew point?
The dew point is the varying temperature at which atmospheric humidity condenses. If the air temperature drops below the dew point, dew and condensation form.
Explain the relationship between condensation and dew point?
Condensation and dew point have a great relationship. Condensation is what happens when dew point temperatures have been reached in an environment.
What happens when air has reached its dew point?
condensation Another question that follows: As an air mass cools to its dew point; relative humidity increases
Describe what happens when water vapor rises and cools to the dew point?
As water vapor cools to the dew point it converts from a gas back to a liquid.
What is the dew point and what happens when it falls below the dew point?
The Dew Point is the temperature at which the air is at 100% Relative Humidity. If the temperature fall below the Dew Point, then there is more moisture in the air than it can hold, and water condenses in the form of dew, mist, rain, etc.
What happens when air that has reached its dew point cooled further?
Condensation
Under what conditions will dew not form?
If the temperature of the ground, grass, and other surfaces is warmer than the dew point of the air that comes in contact with the surfaces, dew will not form. Sometimes this happens when the air is really dry and the dew point is very low.
What happens wen a air mass cools to its dew point?
it grows testicles
What happens when air is cooled below its dew point without condensation?
supercooled
What happens with converging temperature and dew-point spread?
Fog and low clouds
What is the dew point in a hurricane?
there is no dew point of a hurricane
How is dew point different from condensation?
the realationship between condensation and dew point is that condensation occurs when it reaches the dew point.
