Natural Science CLEP Prep Practice Exam

A psychrometer is a scientific instrument designed specifically for recording measurements of temperature, pressure and humidity in meteorology. An anemometer measures wind speed and direction, so it is used to record a different type of data that is not relevant to the question. An altimeter measures altitude, which also is not relevant to meteorology. A hygrometer specifically measures water vapor or humidity, but it does not measure temperature or pressure. Thus, it is not the correct answer for this question.
