INTRODUCTION
Thank you for purchasing General Tools
& Instruments’ EP8711P 6-in-1 In-duct
Digital Psychrometer with Enthalpy. Please
read this user’s manual carefully and
thoroughly before using the instrument.
The EP8711P can measure any

relative humidity (RH), dew point and wet
bulb temperatures, absolute humidity
(mixing ratio) and enthalpy of vaporization.
These measurements are typically made by
three groups of users:
