Pressure CalibratorsFLUKE 750P Series Pressure Modules
Fluke 750P Series Pressure Modules will turn your Fluke multifunction calibrator into a full-fledged pressure calibrator. These flexible modules not only work with multifunction calibrators like the 725, 726 or 750 Series Calibrators but also extend the measurement range of Fluke pressure calibrators. Since the pressure modules are calibrated independently, they can be swapped from one calibrator to another without a loss of accuracy or traceability.
Measuring pressure with Fluke 750P Series Pressure modules is as easy as connecting the module to a pressure source or hand pump, connecting the pressure module cable to the calibrator and then applying pressure from the pressure source. At the touch of a button the measured pressure is displayed digitally on the calibrator in up to 11 different engineering units quickly giving you the data you need. And, with “no tools required” connectors you don’t even need to reach for a wrench to make connections.
When used with the 750 Series Documenting Process Calibrators pressure readings can even be date/time stamped and stored in documented calibration records for later retrieval. This saves time, eliminates errors, and supports compliance with quality standards and regulations.
A complete family of pressure modules
With over 50 pressure modules covering pressure calibration and measurement workloads from 1 inH20 to 10,000 psi (2.5 mBar to 690 bar) finding a model to meet the needs of your specific application is easier than ever. All modules include NPT, metric (BSP) and M20 adapters.

Designed to go where you work
Pressure instruments are often installed in harsh, hard to reach locations, so you need test tools that handle rough service. 750P Series Pressure Modules feature a rugged protective boot that guards the module against shock and seals against dirt and dust, if you accidently drop them, there’s no need to worry. The 750P series modules are also specified across a broad temperature range. Though more accurate across a narrower temperature range if used indoors, these modules are designed and specified to deliver traceable pressure measurements in environments from -10 °C to +50 °C.
