Druck DPI611 Handheld Pressure Calibrator -1 to 1 bar

Key Features:

Compact, handheld design – 50% smaller and 33% lighter than its predecessor, the DPI610 series.

Full self-contained pressure calibration system – Combines pressure generation, signal measurement and loop power in one unit.

Range from -1 to +1 bar (-14.5 to +15 psi) gauge version – Ideal for low-pressure calibrations (also available in other ranges).

High accuracy – Pressure accuracy of 0.0185 % FS (full scale) typical at 10°-30 °C for the -1 to 1 bar range.

Quick pressure generation & vacuum capability – Capable of generating 0 to 20 bar in under 30 seconds, plus 95% vacuum capability for broader calibration tasks.

Simplified touchscreen interface with applications dashboard – Quick task selection, favourites storage and intuitive setup to speed workflow.

Robust and field-ready design – Rugged housing, tool-less quick-fit pressure connection adaptors and ergonomic hand strap make it suitable for on-site calibration.

Electrical I/O and loop power support – Includes measurement/source of mA, V, mV, switch contacts and provides 24 V loop power to support transmitter and loop calibrations.

Data documentation and automation friendly – Features pass/fail error calculation, multi-channel data logging, USB connectivity and compatibility with calibration software (e.g., 4Sight).

Wide environmental and connectivity features – Large colour touchscreen display, USB ports, IP54 rated (dust & splash protected) for reliable performance in the field.
