E-DWT-H is an electronic calibrator designed to replace mechanical, piston-cylinder and weight based deadweight testers. It’s a lighter weight, easier-to-use deadweight tester alternative that is at home in the lab or instrument shop, as well as in the field performing in-situ calibrations and tests.

 

E-DWT-H offers precision, low measurement uncertainty and the stability over time of a conventional deadweight tester without the inconveniences associated with the piston-cylinders, weights, hand pumps, and interconnecting plumbing.

 

    • No weights to load and unload or regularly send out for calibration
    • No need to know and correct for local gravity or ambient temperature
    • No piston-cylinder changes; switch Q-RPT ranges in seconds
    • Not sensitive to level or vibration
    • Able to set and read any pressure value exactly, no minimum increment limited by
      smallest available masses
    • Operates in any unit of measure while deadweight tester is typically limited to the
      pressure unitstamped on the mass
    • Perfect for applications that require setting a nominal pressure precisely on the
      device under test and measuring it, such as analog gauge calibration
    • On-board, AutoTest calibration routines and data acquisition
    • Interfaceable with a PC or laptop to allow for automated data acquisition
    • Two year calibration interval supported at measurement uncertainty of ± 0.025% of reading.
    • Easily recalibrated without crossfloating. Automated calibration of E-DWT-H is
      possible using COMPASS® for Pressure software.
