Analogue or digital pressure gauges are used to make it easier to calibrate an instrument that measures pressure by comparing the value indicated by the latter with the value indicated by the standard pressure gauge, both mounted on a manual or table pump that generates pressure.
Using a pressure gauge makes calibrations easier and more accurate, as you can take as the reference pressure the value indicated on the pressure gauge previously certified by national measuring and calibration centres.
The various kinds of pressure gauges, both digital and analogue, are suitable to solve any problems you may encounter when carrying out calibration in oil or water or aggressive liquids with an operating range from -1 to 7000 bar.
