Extech RH490 Precision Psychrometer with GPP

The Extech RH490 Precision Psychrometer with GPP can measure humidity, air temperature, wet bulb and dry bulb temperature, and mixing ratio. The RH490 displays humidity readings in less than 30 seconds and has data hold and minimum and maximum functions. Users have the opportunity to disable the auto power off function that contributes to its approximately 24-hour battery life. The slim, lightweight meter is designed with rubberized sides and well-spaced buttons that can be used with one hand, even if it is gloved. The weight of water vapor in the air can be displayed in units of Grains Per Pound (GPP) or Grains Per Kilogram (GPK). The RH490 Psychrometer will get the job done in even the most challenging of circumstances.
