The “DewK” Thermo-Hygrometer - Fluke Calibration Instruments - Hart Scientific - #1

Hart Scientific

35 °C. Relative humidity readings are to ± 2%RH from 20 %RHto70%RH

All DewK sensors come with NVLAP accredited certificates of calibration for both temperature and humidity, com­plete with data and NIST traceability. Hart 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 andfrom70%RH to 100%RH are typically within ± 3 %.

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 LogM/are 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.

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 on-screen. Daily summary statistics, including min, max, and maximum rates of change are stored for the most recent sixty days.

Two years ago the 1620 DewK revolu­tionized environmental monitoring for calibration labs, but it just got better. Wait until you hear about the 1620A!

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 LogM/are 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.

Two types of sensors are available from Hart, 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 %RHto70%RH The standard-accuracy sensor ("S" model) reads temperature to ± 0.25 °C over its calibrated range of 15 °C to
