The thermometers are the same, one's bulb is covered in thin cloth called a muslin. The muslin is connected to a water reservoir, and water "wicks" up the muslin, evaporates, and cools the thermometer. So the wet is always (or should be) lower than the dry bulb temp. From the difference (called the wet bulb depression) you can calculate dew point and relative humidity, from printed tables. If the air is dry the depression will be higher (as there is more cooling) while the temps will be close together if the air is moist.
