The 9671 is also capable of measuring relative humidity, wet bulb temperature, dew point and BTU capacity. A built-in sensor records ambient temperature in °F or °C. Model 9671 features include data hold, along with the ability to record minimum, maximum and average readings on a single point. Additional features include an RS-232 interface setting that is engineered to allow the unit to download data, as well as upload up to 99 measurements through pre-edited PC files.
