The UEi DTH35 measures temperature, relative humidity, and calculates wet bulb, dew point, and enthalpy of moist air (air with humidity). The housing design is useful for in-duct measurement, as well as ambient or vent outlet applications. A large, easy to read display, and built in magnet improves ease of use.
