Abstract
A fully-automated handheld pressure calibrator, comprising a housing, and gas circuit and electrical circuit components installed in the housing. The gas circuit components comprise a pressure source capable of supplying a pressurized gas. The gas circuit and electrical circuit components are integrated and installed in the housing in a modular manner, and the shape of the housing is suitable to be held in a hand. The pressure calibrator of the present invention enables all kinds of functions including pressure generation, pressure control, pressure instrument connection, and recording, result calculation, and report output of a pressure calibration process, and is suitable for on-site an on-line calibration of a pressure instrument.
