E-DWT-H breaks new ground in dead weight tester calibration, improving the hydraulic pressure calibration process.
Accuracy and performance
E-DWT can run stand-alone tests and collect test data for dead weight tester calibration. Test data can be downloaded over the RPM4-E-DWT’s RS232 interface.
The RPM4-E-DWT’s RS232 interface can also be used to run the E-DWT with COMPASS® for Pressure software or user developed software.
COMPASS® for Pressure software is universal pressure calibration software for the laboratory, which can be used to run simple or complex tests with multiple instruments. The user can create his/her own calibration report, and data can be exported to Fluke MET/CAL® Plus Calibration Management Software.
Fluke’s calibration, testing and repair services are dedicated to satisfying your needs quickly and at a fair cost while maintaining the unmatched level of quality that is our trademark.
Fluke’s calibration laboratories are accredited by the American Association for Laboratory Accreditation (A2LA) for conformance to ISO Guide 17025.
Fluke Calibration has access to global calibration and repair facilities to keep your dead weight tester and other hardware in top working order.
If you need training for yourself or your staff, Fluke Calibration offers a broad range of classes including: the principles and practices of pressure calibration, advanced pressure metrology, gas flow calibration using a molbloc/molbox system, setup and operation of COMPASS® for Pressure calibration software, and other electrical, temperature and RF calibration topics.
The Fluke Calibratoin commitment to support provides additional benefits as well, including invitations to software user group meetings and conferences, periodic email bulletins and a Fluke Calibration newsletter.
