Ashcroft® Type 1350D deadweight testers provide an easy means of precisely generating pressure to an accuracy of 0.1% of reading.  Ashcroft® 1305D units are available for operating ranges up to 10,000 psi.  They are ideal for use in calibrating, setting, testing and repairing pressure measurement and control devices.  Each 1305D unit is traceable to the National Institute of Standards and Technology, assuring instrument accuracy.
    These pressure systems are designed to be field portable.  A single carrying case holds the pressure generation pump as well as all the necessary tools and accessories.  A second box contains the weights used for pressure generation (10,000 psi units require two boxes of weights).  Ashcroft® deadweight testers qualify as primary standards for pressure calibration.
    The pump is a two-stage hydraulic pressure generator.  A built-in shuttle valve allows for ra
