Pressure CalibratorsFLUKE 729 Pro Automatic Pressure Calibrator
Portable automatic pressure calibrator simplifies pressure calibration
The Fluke 729Pro Automatic Pressure Calibrator has been designed specifically with process technicians in mind to simplify the pressure calibration process and provide faster, more accurate test results. Technicians know that calibrating pressure can be a time-consuming task, but the 729Pro makes it easier than ever with an internal electric pump that provides automatic pressure generation and regulation in an in an easy-to-use, rugged, portable package.
Automatic pressure generation and control
The 729Pro allows you to simply type in a target pressure, and the calibrator will automatically pump to the desired set-point. With plug-in replaceable pressure control modules and pressure generation and regulation up to 1000 psi (70bar, 7000 kPa). Then, internal fine adjustment control automatically stabilizes the pressure at the requested value. You can also fill in a test template and the 729Pro will automatically pump to and document a multiple-point pressure calibration test at the touch of a button.
Easy calibration documentation
The Fluke 729Pro can automatically test multiple pressure test points and automatically document the results. The 729Pro does the work for you by documenting and flagging out-of-tolerance test results in red on the graphical display for:
- Applied pressure
- Measured mA, mV, or digital PV
- % error for each test point
Upload and manage documented calibration results with DPCTrack2™ Calibration Management Software, making it easy to manage your instrumentation, create scheduled tests and reports, and manage calibration data.
HART communication
Built-in HART communication capabilities enable HART transmitter mA adjustments, HART configuration, and the ability to adjust to applied 0% and 100% values. You can also configure various tasks such as changing a transmitter tag, measurement units, and ranging. Other supported HART commands include setting fixed mA outputs for troubleshooting, read device configuration, and variables and read device diagnostics.
Rugged, portable design
The 729Pro is tested and warranted to withstand a 1-meter drop test so it is ready for field instrumentation calibration work. With two models 4M up to 600 psi (40 bar, 4000 kPa), and 7M up to 1000 psi (70 bar, 7000 kPa) to choose from, the Fluke 729Pro Automatic Pressure Calibrators are designed to perform when and where you need them. A standard semi-rigid carrying case designed for field work, with room in the case to store test hoses, fittings, test leads, and small hand tools means it’s easy to carry everything needed for field pressure calibrations.
For greater accuracy and resolution on low pressure calibrations, the Fluke 729Pro allows you to select and insert one of 6 Fluke Pressure Modules to expand the pressure range between 0-600 psi (40 bar, 4000 kPa).

Pressure CalibratorsFLUKE Calibration E-DWT Electronic Deadweight Tester
A modern alternative to the traditional deadweight tester
E-DWT-H breaks new ground, improving the hydraulic pressure calibration process. E-DWT-H is an electronic calibrator designed to replace mechanical, piston-cylinder and weight based deadweight testers. It’s a lighter, easier-to-use deadweight tester alternative that is at home in the lab or instrument shop, as well as in the field performing in-situ calibrations and tests. This complete hydraulic pressure calibration system combines the convenience and precision of continuous, realtime electronic pressure measurement with the simple and direct operation of high quality operator controlled pressure generation hardware. E-DWT-H one year measurement uncertainty is ±0.02% of reading with ranges up to 30,000 psi. It can be configured to provide this uncertainty from its full scale down to 1% of its range. Built-in pressure generation and control hardware allow the operator to fill and prime the system under test and generate and precisely adjust pressure throughout the range with ease.
Broad workload coverage
The E-DWT-H has the operational versatility to calibrate and test a broad range of pressure measuring instruments including:
- Analog gauges
- Transducers
- Calibrators
- Sensors
- Transmitters
AutoTest™ lets E-DWT operators quickly define test points and adjust all of the range-dependent settings with a single function.
The resolution and stability test used by the RPM4-E-DWT are set according to the range of the device under test. The upper limit setting is also set and provides range-based warnings and overpressure protection. While running AutoTests, the operator is prompted to set each sequential test point and test data is stored in the RPM4-E-DWT for recall or download. Typical test setup is quick and easy, but more complex tests can also be stored and reused.
Deadweight tester performance with digital measurement convenience
E-DWT-H offers precision, low measurement uncertainty and the stability over time of a conventional deadweight tester without the inconveniences associated with the piston-cylinders, weights, hand pumps, and interconnecting plumbing.
- No weights to load and unload or regularly send out for calibration
- No need to know and correct for local gravity or ambient temperature
- No piston-cylinder changes; switch Q-RPT ranges in seconds
- Not sensitive to level or vibration
- Able to set and read any pressure value exactly, no minimum increment limited by smallest available masses
- Operates in any unit of measure while deadweight tester is typically limited to the pressure unit stamped on the mass
- Perfect for applications that require setting a nominal pressure precisely on the device under test and measuring it, such as analog gauge calibration
- On-board, AutoTest calibration routines and data acquisition
- Interfaceable with a PC or laptop to allow for automated data acquisition
- Two year calibration interval supported at measurement uncertainty of ±0.025% of reading.
- Easily recalibrated without crossfloating. Automated calibration of E-DWT-H is possible using COMPASS® for Pressure software.
Versatility to cover a broad workload in a variety of environments
The E-DWT-H is at home in metrology and calibration labs, on the production floor or in the field. It operates with Sebacate calibration fluid, mineral oil, Skydrol® and other liquids. An optional battery/charger pack supports up to eight hours of operation away from line power.
