| Abstract: | Present paper describes studies carried out on an industrial dead weight tester (pressure range, up to 330 MPa; calibration; 3 times; period, 6 years), one pressure dial gauge (pressure range, up to 70 MPa; calibration, 3 times; period, 3 years), and one digital pressure calibrator (pressure range, up to 200 MPa; calibration, 4 times; period, 6 years). A small change was observed in the short-term stability but the change was prominent in case of long-term stability in all the instruments. Stability of dead weight tester and pressure dial gauge was well within their claimed manufacturer uncertainties while it was found to be beyond claimed uncertainty in case of digital pressure calibrator. |
