Medela Pump Gauge


Breast pump efficiency is measured by the vacuum (suction) of the pump with this pressure gauge. The gauge measures negative pressure. The gauge needle points to a number from 0 to 450 mmHg (millimeters of mercury – Hg). The reading on the gauge should be compared to the advertised mmHg of the specific breast pump that is being tested, to determine whether the pump is performing to function or not.
