Pneumatic deadweight testers provide a simple-to-use economical solution for pressure calibrations of 14 MPa (2,000 psi) and below. Fluke Calibration’s P3000 series offers flexible options to meet your unique calibration requirements. For vacuum calibrations, Fluke Calibration offers the P3011. For positive pressures up to 3.5 MPa (500 psi), the P3010 series (P3012, P3013, P3014, and P3015) is available. For the most flexibility and capability, the P3020 series handles both positive pressure and vacuum in one package. For pressures up to 14 MPa, the P3030 series uses a liquid lubricated piston / cylinder, providing the ease of use of a hydraulic deadweight tester but with the device under test seeing a gas media. For higher pressures a hydraulic deadweight tester, like the P3100 series, is recommended.
