The DPI 605 precision pressure calibrator combines micromachined silicon piezoresistive
The DPI 605 precision pressure calibrator combines micromachined silicon piezoresistive and resonating element sensors with the latest microprocessor technology, features 0.025% of reading accuracy. It is a totally self contained, battery powered pressure test and calibration system. Standard features include electrical measurement and supply capability, pressure and vacuum generation, simultaneous displays of pressure/vacuum and electrical parameters, extensive data processing and storage capability and RS 232 interface.
The DPI 605 features an impact resistant, splash and dust proof NEMA 4X enclosure. All of the main controls are via a membrane keypad.
Data Log This enables the DPI 605 to act as data logger and store up to 10,000 readings. Record and Replay facilities are included.
