The Fluke MET/CAL compatible 1620A DewK Thermo-Hygrometer revolutionizes environmental mon­itoring for calibration laboratories.
Now you can easily monitor and record conditions through­out your entire facility with the DewK’s new Ethernet and wire­less connections, and set your upgraded LogWare III software to notify you immediately of chang­ing conditions.
You’ll still have the superior convenience, dependability, and NIST-traceable accuracy of a 1620, but your 1620A will give you the added accessibility and peace of mind you’ve been looking for.
Accuracy
Two types of sensors are avail­able from Fluke Calibration, and the DewK may be originally purchased with either one. The high-accuracy sensor (“H” model) reads temperature to ± 0.125 °C over a calibrated range of 16 °C to 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 to 35 °C. Relative humid­ity readings are to ± 2 %RH from 20 % RH to 70 %RH.
All DewK sensors come with NVLAP accredited certificates of calibration for both temperature and humidity, complete with data and NIST traceability. Fluke pro­vides exceptional uncertainties,

including total test uncertainty ratios better than 3:1 for both temperature and relative humid­ity—even for the high-accuracy sensors!
Both sensors can also measure temperature below their respec­tive calibrated ranges to 0 °C and above their respective calibrated ranges to 50 °C with typical accu­racy of ± 0.5 °C. And RH readings from 0 %RH to 20 %RH and from 70 %RH to 100 %RH are typically within ± 3 %.
Ethernet and wireless capability
The DewK gives you all the com­munications options you expect, and then some. With its built-in Ethernet RJ45 jack, multiple DewKs can be monitored from the same screen using our new LogWare III client-server software. Ether­net also gives you the possibility for remote connectivity over the internet, so you can monitor critical conditions while you’re away.
Cables running along the floor can be a safety hazard, and cables hanging from the ceiling and walls are an eyesore. With the DewK, your wireless dreams will come true when you connect your computer through an RF modem up to 100 ft away, without the clutter of all the extra cables!
Finally, if you need a printout, send data to a printer through the RS-232 interface in real time.
Math and statistical functions
In addition to temperature and humidity, the DewK calculates dew point, heat index, and rates of change for both temperature and humidity, without the need to buy additional software. Min, max, and a variety of other statistics are also calculated and can be shown on­screen. Daily summary statistics, including min, max, and maximum rates of change are stored for the most recent sixty days.
The DewK lets you view data just about any way you like it. Both graphical data and statistical data can be shown for temperature and humidity from one or two inputs. Modifying any of the standard screens is easily done, so you see exactly what you want—no more, no less.
Calibrated sensors
With the DewK you get two for the price of one. Having inputs for two sensors, each measuring both temperature and relative humid­ity, one DewK can monitor two locations at the same time. Both sensors can be run via extension cables to remote locations up to 100 feet away, or one sensor can be directly mounted to the top of the DewK.
Each sensor is calibrated for both temperature and humid­ity. The calibration constants assigned to the sensors reside in a memory chip located inside the sensor housing, so sensors may be used interchangeably between different DewKs, and the recali­bration of sensors doesn’t require an accompanying DewK.
Sensors may also be assigned a unique identifier (up to 16 characters) to facilitate record keeping by matching the sensor identifier with the collected data. Each DewK ships with one sensor, with additional sensors available from Fluke. Spare sensors may
also be purchased as a kit, which includes a case for the sensor, a wall mounting bracket, and a 25-foot extension cable.
Memory
The DewK has enough on-board memory to store up to 400,000 date-and time-stamped data points. That’s two years’ worth of data for both measurements from two sensors if readings are taken every ten minutes!
Alarms and battery backup
Alarm settings can be set up quickly in the DewK based on temperature, the rate of change in temperature, RH, the rate of change in RH, and instrument fault conditions. Alarms can be both visual (flashing display) and audible (beeping). Likewise, alarm settings can be set up and events triggered in LogWare III. The DewK is also equipped with a 0 to 12 volt alarm output that can trigger a process control system.
A backup battery shuts down the DewK’s display but maintains measurements for up to 16 hours in the event of a power failure.
One very cool display
Want to view data from across the room? Want to view data from two temperature and two humid­ity inputs simultaneously? Want to view data graphically, statisti­cally, or both? At the same time?! The DewK does everything you could want—or at least everything we could think of. Up to sixteen different display setups can be stored and recalled at the touch of a single button. And all 16 can be easily modified, so you get exactly what you want.
Confidence
Fluke Calibration supplies the world’s finest measurement laboratories with world-class temperature standards. We not only measure temperature and humidity better than anybody, we make temperature measurements functional and productive.
