Fluke Hart Scientific Digital Thermo Hygrometers are Accurate Humidity Measurement Instruments

Fluke Hart Scientific 1620A 1621A 1622A Revolutionize Environmental Monitoring

A little over two years ago Hart Scientific awed the scientific community with the 1620 DewK Thermo Hydrometer as its technology revolutionized environmental monitoring for calibration labs. Well, thys have just made it even better and more accurate. Take a look at Hart Scientific's new 1620A series of Thermo Hygrometers !  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 new Hart Scientific 1620A will give you the added accessibility and peace of mind you’ve been looking for in Temperature Humidity Monitoring Instruments.

Hart Scientific 1620A-S 1620A-H 1621A-S 1621A-H 1622A-S 1622A-H Provide Exceptional Accuracy

Two types of sensors are available from Hart Scientific and the 1620A series can be initially purchased with either sensor. The high-accuracy sensor (“H” model) measures temperature to ± 0.125 °C over a calibrated range of 16 °C to 24 °C. Relative Humidity (RH) 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 Hart Scientific Thermo Hygrometer 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 types of sensors 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 as well as RH readings from 0 %RH to 20 %RH and from 70 %RH to 100 %RH are typically within ± 3 %. 

Wireless Temperature and Humidity Monitoring throughout Your Facility Consoliodated to One Station via Ethernet or Wireless Modem...No Unsightly Cables

The Hart Thermo Hygrometers gives you all the communications options you expect, and then some. With its built-in Ethernet RJ45 jack, multiple Sensing Locations 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 Hart 1620A Series Thermo Hygrometers, 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 are Built into the 1620A series Thermo Hygrometers  

In addition to temperature and humidity, the Hart 1620A 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. 

Calibrated Interchangeable Temperature/Humidity Sensors 

With the Hart Scientific 1620A Series Thermo Hygrometers you get two for the price of one. Having inputs for two sensors, each measuring both temperature and relative humidity, one Hart Scientific Thermo Hygrometer 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 Hart Scientific Thermo Hygrometer. 

Each sensor is calibrated for both temperature and humidity at Fluke’s Hart Scientific Division. 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 Hart Scientific Thermo Hygrometers, and the recalibration of sensors doesn’t require an accompanying Hart Scientific Thermo Hygrometer. 

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 Hart Scientific Thermo Hygrometer is shipped with one sensor and additional sensors are optionally available from Hart. 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. 

The Hart Scientific 1620A Series Contains Memory Galore... for Two Years of Data Storage  

The Hart Scientific Thermo Hygrometer 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! 

1620A's Feature Alarms and Battery Backup 

Alarm settings can be set up easily and quickly in the Hart Scientific Thermo Hygrometer 1620A series 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 software. The Hart Scientific Thermo Hygrometer is also equipped with a 0 to 12 volt alarm output that can trigger a process control system. In the event of a power failure, a backup battery shuts down the Hart Scientific Thermo Hygrometer’s display but maintains measurements for up to 16 hours. 

The 1620A Possess Flexible Multi-Display  Choices

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 Hart Scientific Thermo Hygrometer 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.

The Fluke Thermo Hygrometer 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.

LogWare III Software Personified for the Hart 1620A Thermo Hygrometers If you really want to get the most out of your DewK, LogWare III Software is an investment worth every penny. As client-server or stand-alone software, it remotely monitors and data logs an unlimited number of concurrent log sessions into a single database. That means data from many Temperature Humidity Monitoring locations can be managed in real time via Ethernet, RS-232, or wireless onnections.  LogWare III allows you to customize your graph trace color, alarms, and statistics as you go. You can start/stop log sessions and modify sample intervals from your computer. LogWare III supports “hot-swapping,” which allows you to remove and replace sensors without shutting down the log session. LogWare III also supports security features such as passwords for individual users or groups/teams, a built-in administrator account, pre-defined user groups, and customizable permissions.  Never again be the last to know about a problem. Customizable e-mail settings allow you to send e-mails to designated recipients, including cell phones and PDA’s, when a log session begins, ends, or is aborted; when the DewK’s battery is low; when a sensor calibration is due; or when a temperature/humidity alarm is exceeded.  If you cannot be reached via email, you can always arrange to be paged instead.  Data stored on the DewK can be imported into the software, which is a handy feature when power outages disable the network.  Are you ready for a deep dive into your data? Historical data can be viewed by sensor (model/serial number) location, or log session and displayed in a spreadsheet-style grid. Logged data can also be exported to HTML, RTF or ASCII text for use in your analytical software, or simply print historical data and graphs.  Customizable graphs in LogWare III with zooming capability are an easy way to analyze your data history, and data points that need to be explained can be highlighted, annotated, and referred to later.  LogWare III statistics include min, max, spread, average, and standard deviation functions, and printed reports keep track of the number of temperature and humidity measurements that were found to be out of tolerance.
