Fluke Calibration E-DWT Electronic Deadweight Tester

E-DWT-H breaks new ground, improving the hydraulic pressure calibration process. E-DWT-H is an electronic calibrator designed to replace mechanical, piston-cylinder, and weight-based deadweight testers. It’s a lighter, 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.

This complete hydraulic pressure calibration system combines the convenience and precision of continuous, real-time electronic pressure measurement with the simple and direct operation of high-quality operator-controlled pressure generation hardware. E-DWT-H one-year measurement uncertainty is ±0.02% of reading with ranges up to 30,000 psi.

It can be configured to provide this uncertainty from its full scale down to 1% of its range. Built-in pressure generation and control hardware allow the operator to fill and prime the system under test and generate and precisely adjust pressure throughout the range with ease.
