Keller Pressure Calibrators

Keller pressure calibrators are highly accurate calibration instruments used to generate pressure in order to check and calibrate mechanical and electronic pressure measurement devices with the help of comparative measurements. Available in ranges from vacuum to 700 bar, these calibrators are completely self-contained and can provide power to the transmitter being calibrated, making possible field calibrations in remote locations where power is not available. Keller pressure calibrators are easy to use. Both the pressure generator and the pressure display are integrated into functional housing. The pressure on a test object that is fitted to the calibrator can be built up quickly, and tracking is made easy thanks to the display. Measurement work is made easier by a wide range of functions, such as setting any desired pressure zero point, display of peak and trough pressure values, or leak measurements. Furthermore, the applied pressure can be displayed directly on a computer via the integrated interface (USB converter), after which it can be saved and processed or managed in any desired manner.
