Fluke 6270A

Pressure Controller/Calibrator

The Fluke Calibration 6270A Modular Pressure Controller/Calibrator supports pressure ranges from vacuum to 20 MPa (3000 psi) and accepts up to five interchangeable pressure measurement modules in a single chassis. It offers three accuracy classes, with measurement uncertainty as low as 0.01% of reading depending on module type and range. The system provides automated pressure control, multiple remote interfaces (Ethernet, USB, GPIB, RS‑232), and compatibility with COMPASS for Pressure software for automated calibration workflows. This device, along with the NPT manifold, is perfect for technicians that need to fulfill a variety of requirements.
