The DPI 705 combines outstanding portability with exceptional robustness.

Engineered to fit comfortably in the technician’s hand, this precision instrument is designed for demanding industrial use.
Its light weight, compact design, and intuitive operation make it your constant companion.
At the same time, its splash-proof ABS housing (IP54) provides excellent durability.

The DPI 705 delivers high-accuracy measurements across a wide pressure range.

The large, easy-to-read LCD display shows a 5-digit measurement value.
With a high accuracy of 0.1%, the DPI 705 serves as a reliable pressure reference instrument.
When used with optional pneumatic or hydraulic hand pump connection kits, the unit can be extended into a full-featured calibrator.

As a universal instrument, the DPI 705 is available in ranges from 0–70 mbar up to 0–700 bar.
Versions are available for gauge, absolute, and differential pressure measurement, both with internal and external sensors.
The stainless-steel sensor, manufactured in-house, has proven its reliability in millions of tough industrial applications.

The DPI 705 supports your applications with convenient functions.

The following features enhance flexibility for daily measurement tasks in plant engineering, service, production, and development:
Selectable at the touch of a button:

16 pressure units: mbar, bar, psi, Pa, kPa, MPa, kg/cm², in Hg, mmHg, mH₂O, inH₂O, ftH₂O (both at 4° and 20 °C)

Intrinsic Safety Version

With the intrinsically safe version DPI 705/IS, new possibilities open up for the user.
Lengthy applications for Ex entry permits are no longer required — with the DPI 705/IS you can safely operate even in Ex Zone 0.

Pressure Ranges

The version with an internal pressure sensor features a G⅛ female pressure connection; a 6 mm hose adapter is pre-installed.
The version with an external pressure sensor uses an electrical connector with a 1 m cable.
All sensors have a G¼ female pressure connection.

Ordering Information

1. Select standard (DPI 705) or intrinsically safe (DPI 705/IS) version.
2. Select internal or external pressure range according to the table.
   Note: the instrument supports only one range.
3. Select gauge, absolute, or differential pressure type.
4. Add desired options (A1)–(A4), (B), (D).

Scope of Delivery

The DPI 705 is supplied complete with an operating manual and calibration certificate.

Traceability

All calibration data are recorded using instruments maintained under an ISO 9001 quality system and are therefore traceable to national standards.
