dry bulb thermometer

A dry bulb thermometer is used to measure the ambient temperature.

Measure the air temperature with an ordinary dry bulb thermometer in various locations.

A wet bulb and a dry bulb thermometer are used.

The sensible heat of the incoming air, as measured by a dry bulb thermometer, is reduced.

A dry bulb thermometer is a device that measures air temperature independently of humidity.

The thermometer therefore indicates a lower temperature than that of the dry bulb thermometer.

For fire purposes we use a wet and dry bulb thermometer, discussed below for humidity. 2.4.2.

After resetting, the maximum thermometer reading will be within 0.5 degrees of the dry bulb thermometer reading.

It is a measurement of heat intensity independently of humidity and a dry bulb thermometer is used to measure it.

Psychrometers (Wet and Dry Bulb thermometer)

On Auxiliary Ships, only the dry bulb thermometer is required, so one thermometer is removed from the sling and used as a spare.

Psychrometers At Canadian stations, using ventilated psychrometers, the wet bulb and dry bulb thermometers are mounted vertically in a Stevenson screen.

There are several methods of measuring temperature and relative humidity, ranging from a simple thermometer for temperature and a wet and dry bulb thermometer (psychrometer) for humidity to sophisticated electronic instruments equipped with solid state sensors.

At freezing temperatures, a layer of ice within the muslin of the wet bulb thermometer must have formed about ten minutes before the actual observation can be taken. The portable sling psychrometer has a wet bulb and a dry bulb thermometer mounted side by side on a frame.

But from this point his experiences should be gathered from his own words:-- "About 1.52 p.m., or later, I read the dry bulb thermometer as minus five; after this I could not see the column of mercury in the wet bulb thermometer, nor the hands of the watch, nor the fine divisions on any instrument."

He looked doggedly through the sheets of physical observations he had made for Humboldt, temperature and salinity of the sea at various depths, barometric pressure, temperature of the air by wet and dry bulb thermometer, a chain of observations more than half way round the world, and he derived a certain satisfaction from them.
