Pressure Calibrators

Handheld pressure calibrators (Hand pump calibrators) are portable manual pressure sources used for the calibration of pressure measurement devices by means of the comparative measurement method. Simple and precise pressure adjustment can be easily achieved using the integrated fine adjustment valve. Models are available that operate with both pneumatic (ambient air) and hydraulic (oil or water) methods. When the device under test and the reference device are connected to the same pump, they are subjected to the same pressure, and by comparing the measurement results, the accuracy or adjustment of the device can be verified. This ensures reliable calibration of instruments such as pressure gauges and pressure transmitters, both in the field and in laboratory environments.
