A highly accurate and easy to use calibrator for improving overall data quality and working efficiency. The DPI 611 is the fourth generation in the DPI 600 family and is 50% smaller and 33% lighter than the DPI 610, generates 0 to 20 bar/300 psi in less than 30 seconds and creates 95% vacuum. Pressure measurement is twice as accurate, three times better electrical accuracy and has a simplified touch screen interface. The DPI 611 is a simple-to-use “everyday” tool for maintaining and calibrating pressure instruments. It also has the advanced features of the DPI 620 Genii for automating calibration procedures, calculating errors and interfacing with PCs and calibration and maintenance systems.
