With the PCE-555 Hygrometer you can measure ambient conditions including humidity in the top portion of the LCD whilst temperature is shown at the bottom. It also calculates wet bulb temperature and dew point, which are useful for calculating thermal stress. Dry bulb temperature is simply the environmental temperature. It's the temperature that is measured using any kind of thermometer. Wet bulb temperature is determined by using a mercury thermometer which is situated in the shade with the bulb covered with a piece of wet fabric under a current of air, measuring, for example, a vent or a rotating electric fan. In this way, the evaporation of water absorbs heat lowering the temperature, reflecting the decrease in the temperature reading. The lower relative humidity is, the quicker the water in the fabric will evaporate and the further the resulting decrease with respect to the dry bulb temperature (this is used to give an idea of thermal sensation). Dew point is the temperature at which air vapour turns into condensation, producing dew or mist, or if the temperature is low enough, frost.
