What scientific instrument measures dew point?
the dew pt. hygrometer is a good answer but is no longer in use. dew point is messured by a mathamatical equation based on tempature, pressure and relitive humidity a hygrometer is used to optain the humidity leval. the dew point hygrometer is out dated and not used any longer due to the development of more sophisticated equipment. the hygrometer is now basicly a device that mesures Tempature and humidity along with the thermometer and barometric pressure they use a formula to obtain dew pt. here is a link to the formula for Relative Humidity and Dewpoint Temperature from Temperature and Wet-Bulb Temperature http://www.srh.noaa.gov/elp/wxcalc/formu… Wet-Bulb Temperature and Relative Humidity from Air Temperature and Dewpoint Temperature http://www.srh.noaa.gov/elp/wxcalc/formu… Wet-bulb Temperature an
