Accurate enough for lab use, and rugged and portable enough to take anywhere
• Best-performing industrial heat sources (accuracy, stability, uniformity) in the world
• Immersion depth to 203 mm (8 in)
• Optional ITS-90 reference input reads PRTs to ±0.006 °C
• Temperature range from –45 °C to 700 °C

Every once in a while, a new product comes around that changes the rules. It happened when we introduced handheld dry-wells. It happened when we introduced Micro-Baths. Now we’ve combined bath-level performance with dry-well functionality and legitimate reference thermometry to create Metrology Wells.

With groundbreaking new proprietary electronics from Fluke Calibration's (patents pending), Metrology Wells let you bring lab-quality performance into whatever field environment you might work in. New analog and digital control techniques provide stability as good as ±0.005 °C. And with dual-zone control, axial (or “vertical") uniformity is as good as ±0.02 °C over a 60 mm (2.36 in) zone. (That’s 60 mm!) Such performance doesn’t exist anywhere else outside of fluid baths.

In short, there are six critical components of performance in an industrial heat source (which the European metrology community explains, for example, in the document EA-10/13): calibrated display accuracy, stability, axial (vertical) uniformity, radial (well-to-well) uniformity, impact from loading, and hysteresis. We added a seventh in the form of a legitimate reference thermometer input and created an entirely new product category: Metrology Wells.

(By the way, Metrology Wells are the only products on the market supported by published specifications addressing every performance category in the EA-10/13. Our specs aren’t just hopes or guidelines. They apply to every Metrology Well we sell.)

Automatically generates and controls pressure up to 300 psi (20 bar, 2 MPa). Enter the pressure and the 729 will automatically pump to the desired pressure. Fill out the test template and the 729 will automatically pump and document pressure calibration tests at multiple points.



Easy calibration documentation using predefined templates for transmitters and switches. Enter the initial and final test pressures and the number of test points. The rest of the 729 did by documenting the applied pressure, the measured mA, and the % error of each test point. The bright color graphics display will highlight the tolerance test results in red.



Automatic fine adjustment of internal pressure helps compensate for minor leaks in hoses and test settings. There is no need to manually turn the vernier to check for leaks, helping to eliminate the hassle of manual pumping and manual fine adjustment of test settings.



HART communication allows trimming of mA output, trimming to applied value, and trimming to zero pressure from HART pressure transmitters. You can also perform light configuration tasks such as changing transmitter tags, units of measurement, and setting ranges. Other supported HART commands include setting a fixed mA output for troubleshooting, reading device configurations and variables, and reading device diagnostics.



Measures mA signal at transmitter source output and simulates mA signal for testing I/Ps and other mA loop devices. Includes a 24V loop power supply to test and power transmitters in self-tests not connected to a control system.



Rugged portable case design 3 year warranty sets the 729 apart from most other pressure calibrators. The 729 is tested and guaranteed to withstand a 1 meter drop test, making it ready for field instrumentation calibration work.



Fluke Connect® compatibility allows users to remotely monitor using the Fluke Connect mobile app as well as manage and store pressure measurements and log events. Share measurements using ShareLive™ video calls and email.



Measure temperature with the optional 720RTD probe to perform resistance transfer calibration.



Measure pressure with the old 700 Series and new 750 Series pressure modules if a different pressure measurement range or resolution is desired.



Multiple language support : select the language from the instrument setup utility. Hart communication commands are limited to English per HART device description and protocol.



The rigid yet flexible carrying case is designed for field work, with room in the bag for storing, test hoses, fittings, test cables and small tools needed for field pressure calibration.



Portable automatic pressure calibrator makes pressure calibration easy



The Fluke 729 Automatic Pressure Calibrator has been specifically designed with the work of process technicians in mind to simplify the pressure calibration process and provide faster, more accurate test results. Technicians know that calibrating pressure is a time-consuming task, but the 729 makes it easier than ever with an internal electric pump that generates and adjusts pressure automatically in a rugged, easy-to-use portable package.



The 729's ideal portable pressure calibrator, allows you to simply enter a target pressure, and the calibrator will pump automatically at the desired set point. Then, an internal fine adjustment control automatically stabilizes the pressure at the set value.



The Fluke 729 can also test multiple pressure test points automatically and automatically document the results. Calibration is as simple as entering the initial and final pressures as well as the number of test points and tolerance levels. The remaining 729 do.



Built-in HART communication capability allows for mA tuning of HART transmitters, lightweight HART configuration, and the ability to adjust to applied 0% and 100% values.



Upload and manage documented calibration results with DPCTrack2™ Calibration Management Software, making it easier to manage your instrumentation, create scheduled tests and reports, and manage calibration data.



With three selectable ranges, 30 psi (2 bar, 200 kPa), 150 psi (10 bar, 1 MPa), and 300 psi (20 bar, 2 MPa), the Fluke 729 Automatic Pressure Calibrator is designed to work anytime, anywhere. wherever you need it.
