Pressure CalibratorsFLUKE 700PRV-1 Pressure Relief Valve Kit
The Fluke 700PRV-1 consists of a relief valve settable from 725 to 5800 PSI (50 to 200 bar) to be used with the 700HTP-1 Hydraulic Test Pump. The 1/8” NPT male thread to fits directly into the Fluke 700HTP-1 pressure pump.
To be used with the 700HTP-1 Hydraulic Test Pump. The 700PRV uses a multi-turn adjustment screw to set preload on internal disc springs. This relief valve will protect the most commonly used Fluke pressure modules and pressure instruments from damage due to accidental over-pressurization.

Pressure CalibratorsFLUKE Calibration P3100 Hydraulic Deadweight Testers
The P3100 models are available in single or dual piston format. Unit can be supplied in psi, bar, kgf/cm², and MPa. This robust instrument is highly accurate, quick and easy to use. Units feature a built-in priming pump for large volume applications, piston flotation indicators and a high quality screw press for fine pressure control.
Operating principle
Deadweight testers are the high performance pressure standards for pressure measurement. Utilizing the well proven piston-gauge system consisting of a vertically mounted, precision lapped piston and cylinder assembly, accurately calibrated weight masses (Force) are loaded on the piston (Area), which rises freely within its cylinder. These weights balance the upward force created by the pressure within the system. The pressure is measured when placed on a correctly spinning and floating piston. The total pressure measured is the summation of the weights plus the piston weight carrier assembly.Instrument base
There are three basic variations in the hydraulic offering; single low pressure, single high pressure and dual piston models. Pressure is generated and controlled by means of a high quality screw press located on the front of the tester. A built-in hand pump is included as standard for all hydraulic models to prime the system and accommodate large volume requirements.
Piston/cylinder assemblies
The piston/cylinder assembly is the heart of each deadweight tester. They are manufactured from materials that provide stability, durability, and low thermal coefficients and distortion. Our experience and knowledge of piston/cylinder production and calibration ensure the precision and performance required for today’s demanding calibration requirements.
Weight masses
Standard weight masses are series 3 nonmagnetic austenitic stainless steel. Each mass is marked with the serial number of the instrument and the nominal pressure value relative to the high or low-pressure piston, when applicable. Optional fractional weights are stainless steel and/or solution heat treated aluminum.
Gravity correction
Gravity varies significantly with geographical location and this variation has a direct effect on the force of the weights and the accuracy of the deadweight tester. Each instrument can be calibrated to local gravity at no extra cost. If unspecified, instruments will be calibrated to Standard Gravity at 980.665 cm/s2.(0 reviews) -

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).
