Electronic pressure controllers eliminate the droop and hysteresis associated with traditional mechanical spring diaphragm pressure regulators. And, choosing a metal sealed pressure controller brings enhanced purity of the gas due to elimination of oxygen permeation through elastomers, with a reduction in maintenance since metal seals will last indefinitely.

Brooks pressure controllers are available with internal pressure sensors to control pressure in a range from torr to 500 psig. The result: pressure controllers that keep critical semiconductor processes on-target and under the most stringent control – hour after hour, day in and day out.
