Multifunction CalibratorsFLUKE 754 Documenting Process Calibrator-HART
Fluke 754 Documenting Process Calibrator with HART communication does the work of many tools
Whether you’re calibrating instruments, troubleshooting a problem, or running routine maintenance, the Fluke 754 with HART® communication can help you get the job done faster. It does so many different tasks, so quickly and so well, it’s the only process calibrator you need to carry. This rugged, reliable integrated communicating calibrator is ideal for calibrating, maintaining, and troubleshooting HART and other instrumentation.
The 754 is a power multifunction documenting calibrator that you can use to download procedures, lists, and instructions created with software; or upload data for printing, archiving, and analysis. The powerful built-in HART interface is capable of performing nearly all the day-to-day tasks you now perform with a separate communicator.
In fact, the 754 does the work of several tools. It sources, simulates and measures pressure, temperature, and electrical signals with one rugged, hand-held device. For documentation, the 754 automates calibration procedures and captures your data. And, of course, it helps you meet rigorous standards like ISO 9000, FDA, EPA and OSHA regulations. Plus, the new improved graphical screen, Li-Ion battery for longer life, USB port, and accessories help you work smarter and faster.
To create a seamless/paperless calibration management system consider adding Fluke DPCTrack2 Calibration Management software for use with your Fluke 753 and 754 or even legacy Fluke 743 and 744 calibrators.
Other useful features:
- Handles fast pulsed RTD transmitters and PLCs, with pulses as short as 1 ms
- Measures/sources pressure using any of 29 Fluke 700Pxx Pressure Modules
- Creates and runs automated as-found/as-left procedures to satisfy quality programs or regulations, and records and documents results
- Holds up to a full week of downloaded procedures and calibration results
- Uses many features like autostep, custom units, user-entered values during test, one-point and two-point switch testing, square root DP flow testing, programmable measurement delay and more
- Provides easy-to-use multi-lingual interface
- Features a bright white dual display for reading both sourced and measured parameters simultaneously
- Includes rechargeable Li-Ion battery for 10 hour uninterrupted use
- Comes with three-year warranty and DPC/Track Sample software
- Offers compatibility with many asset management software packages

Temperature CalibratorsFLUKE Calibration 1620A Precision Thermo-Hygrometer
Accuracy
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.
Ethernet and wireless capability
With its built-in Ethernet RJ45 jack, multiple DewKs can be monitored from the same screen using Log Ware 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, simply connect your computer through an RF modem up to 100 ft away, without the clutter of all the extra cables.
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. 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 sensors
With 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 by Fluke Calibration. 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 directly from your local Fluke Calibration sales representative, or directly from Fluke Calibration. Spare sensors may also be purchased from Fluke Calibration 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 times 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 Log Ware 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.
Large, easy-to-read 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.

What is a Blackbody Calibrator?
A blackbody calibrator (or blackbody source) is a device that emits thermal radiation with high emissivity, typically near 1.0. This makes it behave closely to an ideal blackbody, emitting radiation according to Planck’s law.
Blackbody calibrators are essential tools for ensuring the accuracy of:
- Infrared thermometers
- Thermal imagers
- Non-contact temperature measurement devices
By aiming a device under test at the precisely controlled blackbody target, users can verify and adjust readings to ensure accuracy and compliance with calibration standards.
