Keller pressure calibrators are high-accuracy calibration instruments, designed for comparative calibration of mechanical and electronic pressure measuring devices via precision controlled pressure generation. Available in pressure ranges from vacuum up to 700 bar, these fully self-contained calibrators can supply loop power to the transmitter under test, enabling field calibrations in remote locations with no access to mains power.

Keller pressure calibrators feature an intuitive, easy-to-use design, with the pressure generator and high-accuracy pressure display fully integrated into a compact, functional housing. Pressure can be built up quickly on the test device connected to the calibrator, with real-time pressure values displayed for easy tracking. A full suite of functions simplifies measurement work, including user-settable pressure zero point, peak and trough pressure value recording, and integrated leak measurement. Additionally, the applied pressure can be transmitted directly to a computer via the included integrated USB converter, for data saving, post-processing, and asset management.
