HigH-pressure calibrator
medium: Hydraulic oil / up to 700 bar
KELLER pressure calibrators are highly accurate calibration instruments which are available for
the following pressure ranges: -0,85…10 bar (LPX), -0,85…25 bar (MPX) or 0…700 bar (HPX)
(special measurement ranges are available on request).
The high-pressure calibrator (HPX) is used to generate pressure in order to check and calibrate mechanical and electronic pressure measurement devices with the help of comparative
measurements.
The pressure generator is accommodated together with the pressure display in a functional
housing. The pressure on a test object that is tted to the calibrator can be built up quickly, and
tracking is made easy thanks to the integrated display.
Test objects with a G 1/4” thread can be connected directly to the pressure port for the test
object
. The pressure is built up and adjusted precisely via a screw compressor that is integrated in
the device (medium: hydraulic
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.
oil).

The calibrator, including accessories, is supplied in a durable carrying case, making it ideal for
assignments in the eld.
