New: E-DWT-H™ Electronic Deadweight Tester
DHI’s new E-DWT-H™ Electronic Deadweight Tester combines pressure generation, control, and digital measurement into a portable, rugged and lightwieight package

DH Instruments, a Fluke Company, announces the E-DWT-H™ electronic deadweight tester, a modern alternative to the conventional deadweight tester. E DWT-H is designed to provide an easy-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.

The E-DWT-H’s electronic reference pressure monitor can be configured with one or two internal ranges from 7 MPa (1,000 psi) to 200 MPa (30,000 psi). With two internal ranges, the E DWT-H provides uncertainty of ± 0.025% of reading from 1 to 100% of full scale range.

The E-DWT-H includes exclusive, individually characterized, quartz reference pressure transducer (Q-RPT) modules for increased precision and reduced measurement uncertainty. The AutoRange™ feature optimizes measurement, control and safety features for the specific range of the test being run with a few simple entries. Its ready indication provides straightforward feedback that allows for consistent results during each test.

The E-DWT-H eliminates the need for weights and the associated handling chore, as well as possible errors and shipping costs. With E-DWT-H there is no need to measure ambient conditions and piston temperature, to know local gravity when trying to accurately measure pressure or to ensure that the unit remains level. Electronic output allows for active pressure display, unlimited pressure resolution, AutoTest calibration routines, real time automated data collection and customized report generation. Simple and free embedded software upgrades are available from DHI.

The E-DWT-H is designed for lab, shop or field use. All features expected in high-end calibration equipment are in this lightweight, rugged and portable calibrator. Available batteries make remote use possible. An optional rugged, wheeled case allows quick setup and makes transport easy and worry free.
