Preliminary assessment of the out-of-box capabilities of the two electrical pumps in this study indicated the maximum vacuum pressure level common to both pumps was 57.6 kPa (17 inHg).
The exhaustive testing for each pump involved evacuating the 106 [cm.sup.3] (6.46 [in..sup.3]) chamber repeatedly to 57.6 kPa (17 inHg), allowing only time to return the chamber to the baseline atmospheric pressure between each evacuation trial, until the Li-Ion battery of the pump was depleted.
Maximum flow is 3.5 to 12.0 [m.sup.3]/hr (2.06 to 7.6 cfm); maximum pressure to 1.0 bar (14.5 psig) and maximum vacuum to 150 mbar abs (25.1 inHg

The barometer measures pressure from 23.62 to 31.01" of mercury (inHg
) with a resolution of 0.03 inHg
, and from 800 to 1050 mbar with a resolution of 1 mbar.
While most pumps require at least 59 to 87 psi, the P2010 can generate a vacuum of 24.9 inHG
at a feed pressure of only 26 psi, reducing compressed air costs by up to 50 percent.
The barometer measures pressure in 3 different units: inches of mercury (inHg
) from 0.29 to 32.48 with a resolution of 0.01, millibars (hPa) from 10.0 to 1100 with a resolution of 0.1 and 1 hPa, and millimeters of mercury (mmHg) from 7.5 to 825.0 with a resolution of 0.1 mmHg.
The barometer measures pressure from 23.45" to 31.01" of mercury (inHg
