The Fluke 1620A (DewK) thermo hygrometer and humidity monitor measures temperature to +/- 0.125°C and humidity to +/- 1.5% on two channels, and displays it on a big, clear screen. Ethernet, wireless (optional), or RS-232 will allow you to network as many Fluke 1620s (DewKs) as you’d like. And the LogWare III software will allow real-time logging of multiple Fluke 1620s (DewKs), data storage to your computer and seamless integration with MET/CAL® software.

The high-accuracy sensor (“H model) reads temperature to +/- 0.125°C over a calibrated range of 16°C - 24°C. Relative humidity readings are to +/- 1.5% RH from 20% RH to 70 % RH.  The standard-accuracy sensor (“S model) reads temperature to +/- 0.25°C over its calibrated range of 15°C - 35°C. Relative humidity readings are to +/- 2% RH from 20% RH to 70% RH.

All Fluke 1620A (DewK) thermo-hygrometer sensors come with NVLAP accredited certificates of calibration for both temperature and humidity, complete with data and NIST traceability.
