Fluke 1621A-S DewK Thermo-Hygrometer Datalogger

The 1621A-S "DewK" Thermo-Hygrometer with LogWare III Software accepts inputs from up to two sensors, which may be mounted directly on the unit or remotely (up to 100 feet away). Each sensor comes with a NVLAP-accredited calibration for temperature and relative humidity from Fluke Calibration, containing its own NIST-traceable calibration data, so recalibration doesn't require the main unit.
 

Now you can easily monitor and record conditions throughout your entire facility with the DewK's new Ethernet and wireless capabilities, and set your upgraded LogWare III software to notify you immediately of changing conditions.
