The 3130 digital pressure calibrator from Fluke (Everett, WA) contains everything needed to generate, control, and measure pressure, as well as read the output of the device under test, says the company. It includes an onboard pressure sensor with a full scale of 2 MPa (300 psi, 20 bar) and an accuracy of 0.025 percent, reading plus 0.01 percent FS. The portable pressure calibrator features an internal, motorized pump providing an efficient alternative to time consuming, tiring hand pumps. For applications that involve filling a large volume with pressure, the 3130 allows for connection to an external gas supply, such as compressed plant air or gas cylinder, to supply pressure up-to-300 psi.
